Who—or what—might be here?

The extraterrestrial hypothesis deserves serious consideration. So do the strongest claims made by officials who say that non-human activity has already been established within restricted settings. Their statements change the questions that investigators should pursue. They do not require every UAP, every encounter with a presence and every account of hidden knowledge to have the same origin.

This chapter compares seven families of explanation. They are not assigned equal probabilities. Some invoke processes demonstrated in particular circumstances; others propose possibilities for which decisive evidence is still sought. Their usefulness depends on which observations they explain and what could distinguish them from alternatives.

1. Separate existence, agency and origin

An unusual observation raises several questions in sequence.

Was there a physical target? A correlated external measurement can help distinguish a target from a camera effect or a private experience. It still needs to be associated with the event correctly.

Was its behaviour controlled? A specific, repeatable response to changing circumstances could support control. Control might be exercised by an occupant, a remote operator or an automated system.

What made it? Establishing technological behaviour is different from identifying a manufacturer. Something unfamiliar to an observer is not automatically beyond all human capability.

Where did it originate? “Not identified as ours”, “not known to this agency”, “not human-made” and “from another planet” are progressively different claims. An institution can be uncertain at one level while an individual advances a stronger assessment.

These distinctions allow a discovery to develop. A clearly controlled object could be established before its makers are known. A material could reveal manufacture before a civilisation is identified. An apparent intelligence could communicate before its claims about origin are verified.

The investigation should preserve each advance without making it carry every subsequent conclusion.

A shorter comparison of Ra’s orientation map and Bashar’s ancestry map is kept at Who they are. The portraits are gathered under Reported beings and identities.

2. What senior officials add to the origin question

Officials can contribute something unavailable through open skywatching: programme access, protected disclosures, operational records and knowledge of what particular organisations have investigated.

The film-related statements reviewed in Chapter 2 include a claimed personal observation, allegations about possession and programmes, and accounts of information handling. These are substantial claims to pursue. Their different routes of access should remain visible when considering origins.

Karl Nell offers an especially explicit public position. In his May 2024 SALT conversation, he asserts that non-human intelligence exists and has interacted with humanity over time. Asked about the basis of his confidence, his public explanation includes statements by other people with relevant access and a broader argument about life and intelligence. This is a clear declaration of conviction, with public reasoning to examine; it is not an exhibited specimen or a new sensor dataset. [1]

Rubio's later clarification illustrates a different position: concern about received allegations and unexplained incursions without claiming personally verified programme knowledge. The difference between these positions must not disappear inside a montage of senior faces. [2]

AARO's 2024 historical assessment states that it found no evidence confirming extraterrestrial technology in the investigations it reviewed and no empirical support for the reverse-engineering narrative examined. That is a substantive institutional disagreement with stronger insider allegations. [3]

The disagreement creates research obligations on both sides. Claimants should identify the most specific supporting records they can lawfully make available. An investigating office should explain its access, methods and case-specific findings as far as possible. Credentials and institutional authority can guide where to look; they cannot replace the material that resolves the conflict.

3. Visitors or probes from beyond Earth

The extraterrestrial hypothesis proposes that at least some encounters involve technology or beings originating beyond this planet. It is compatible with several kinds of visitor: biological travellers, autonomous probes, remote instruments or systems left nearby long ago.

This range matters. A distant technological civilisation would not need to send a representative shaped like a human, or establish a public relationship immediately. Its local equipment might act independently. A recovered machine, if established, would therefore not automatically establish the presence of a living crew.

The hypothesis offers a possible explanation for securely demonstrated capabilities beyond identified human engineering. It can also address an encounter containing unfamiliar occupants. But each proposed application requires the relevant performance or biological observation to be established first.

What would distinguish an extraterrestrial origin? Potential evidence includes an authenticated artefact whose manufacture and history cannot be accounted for terrestrially, biological material with a well-established non-terrestrial provenance, or communication providing independently verified information about its source. Several independent lines would be more persuasive than one ambiguous clue.

Unusual composition alone is insufficient. A natural meteorite has an extraterrestrial origin without being technology. An engineered object may be terrestrial even if its composition is unfamiliar. The crucial inference connects provenance, manufacture and context.

NASA's 2023 team did not find conclusive evidence in the literature it reviewed that UAP have an extraterrestrial origin. Its recommendations nevertheless support developing observations capable of testing the question. Scientific uncertainty can coexist with an important research target. [4]

4. Future or parallel humanity

A different proposal begins with the recurring humanlike form of reported beings and their apparent interest in human bodies or history. Perhaps some visitors are related to us rather than arriving from an unrelated evolutionary history.

Anthropologist Michael Masters presents a future-human hypothesis in Identified Flying Objects: descendants could be returning to study their own past. His faculty-page description identifies this as the premise examined by the book. It does not report a demonstration of time travel. [5]

The proposal connects several narrative features elegantly: resemblance, familiarity with human life and repeated interest in ancestry. Those connections make it worth articulating clearly. They are not specific enough on their own to distinguish future descendants from fictional imagery, misperception, shared ancestry of another kind or an interpretation imposed after the event.

A biological resemblance is especially limited as a clock. A large head or small face cannot reliably identify a being as a later stage of human evolution. An evolutionary story needs evidence for an actual lineage, rather than extrapolation from a few selected traits.

A stronger test would seek detailed, independently checkable information or material establishing the proposed relationship. Information allegedly from the future should be recorded before events occur, with clear criteria for agreement and failure. An ability to describe present secrets would test access to information before it tested time travel.

Parallel humanity is another proposal, involving another history rather than a later point in our own. It should be stated separately. Changing from a future to a parallel-world explanation after a prediction fails may preserve a story, but weakens the value of that prediction as a test unless the possibilities were bounded beforehand.

5. Intelligence associated with other states of reality

Some sources describe appearances, communication and travel through a reality broader than ordinary physical experience. This family includes claims about other dimensions, nonphysical consciousness and realities accessible in unusual states of awareness.

Ra's travel account includes thought-related movement and forms that do not fit a conventional interstellar journey. Bashar's basic principles place consciousness and the structure of experience at the centre of their explanation. These are metaphysical accounts to investigate, not measurements of additional dimensions in a particular encounter. [6] [7]

The attraction of the family is its capacity to address more than a flying object. It can include apparently meaningful communication, discontinuous appearances and experiences felt to occur outside ordinary space or time.

The difficulty is making the proposal discriminating. “Another dimension” does not specify a mechanism by itself. What information or interaction crosses the boundary? Under which conditions? What would distinguish it from an unusual human experience, deception or an unfamiliar physical process?

One promising question is whether an experience includes verifiable information inaccessible by ordinary means. Another is whether independent instruments record a corresponding physical effect. These would be different findings: information transfer and physical interaction. Neither would identify a complete cosmology without further evidence.

Inner experience should also retain its own integrity. A profound sense of unity need not be converted into a spacecraft claim to deserve philosophical or spiritual attention. Conversely, a spiritually resonant explanation should not prevent a physical recording from receiving an ordinary technical analysis.

6. An unrecognised terrestrial intelligence

The cryptoterrestrial hypothesis proposes a concealed intelligence associated with Earth or its immediate environment. It differs from a transient visitor: the proposed presence may have been here for a long time.

Lomas, Case and Masters explored this family in a 2024 paper. Their opening note calls it a speculative thought piece, disclaims association with Harvard's Human Flourishing Program and says they regard the hypothesis as likely false while still worth investigating. Those qualifications are part of the paper, not later objections imposed on it. [8]

An Earth-associated intelligence might be proposed to explain reports concentrated around oceans, apparent long continuity or an elusive local presence. None of these observations establishes a habitat. Being seen over the sea is not evidence that an object lives beneath it; an old story is not automatically a record of the same agent seen today.

The hypothesis opens practical questions. Where is the physical activity? What traces would a sustained technological population leave? What distinguishes its materials, infrastructure or ecology from human activity? If it is proposed to be almost undetectable, which observations are still predicted?

A concealed population cannot be inferred solely from gaps in human exploration. Unexplored space offers an opportunity to investigate, not a positive identification of an inhabitant.

This family should also remain distinct from a surviving ancient human civilisation. That proposal makes archaeological and historical claims about human continuity. A non-human terrestrial species makes additional biological and ecological claims. Each needs evidence suited to its own history.

7. Human technology and information operations

Some unfamiliar objects may be human systems whose purpose, capabilities or identity are restricted. Drones, balloons, aircraft and electronic systems provide several different possibilities. They should be compared case by case rather than offered as one universal answer.

There is also a documented history of concealment. CIA historian Gerald Haines describes misleading public explanations used to protect reconnaissance programmes. That establishes that government management of UFO reporting has sometimes concealed human technology. It does not establish that every unexplained encounter was a secret aircraft, or that every retrieval allegation was a deliberate deception. [9]

An unusually capable classified human platform would be a major finding. But “classified” should not function as unlimited permission to invent capabilities. A proposed aircraft still needs to account for the actual track, signatures, operation and historical period.

Information operations require their own evidence. A false explanation can arise through deliberate fabrication, mistaken analysis, bureaucratic misunderstanding or sincere repetition. Demonstrating one of these does not automatically demonstrate the others.

Seek specific records: programme documents, engineering history, identified hardware, communication plans or a traceable source of fabricated material. A government denial should be assessed against those records. An allegation of disinformation should also identify what was false and how its production or distribution is known.

The possibility that human and unfamiliar activity coexist should remain available. A real classified programme could generate misleading interpretations while an unrelated encounter remains difficult. One explanation need not own the entire subject.

8. Natural, instrumental and human experiential processes

Some cases become clearer when the observing system is reconstructed. A moving aircraft, uncertain range and camera tracking can make an ordinary target appear extraordinary. AARO's GoFast analysis is a published example of that kind of explanation; Chapter 3 discusses its inputs and limitations. [10]

Other cases concern unusual experiences rather than images. Sleep-paralysis research documents recurring presence and bodily experiences in a defined physiological setting. It supplies a comparison when an encounter occurs near sleep, not an explanation for every report of an intelligent presence. [11]

These explanations deserve the same specificity demanded of an extraterrestrial proposal. Was the observer actually at a sleep–wake boundary? Does the optical model reproduce the sequence? Does a proposed astronomical object fit the location, time, motion and duration?

A familiar label can be used too quickly. “Balloon” is a hypothesis until its size, motion and appearance fit. “Hallucination” does not explain a case merely by naming the possibility of perception without an external object.

Equally, a person's sincere certainty does not exclude an ordinary process. The aim is not to decide whether an experience was important to the person. It is to determine which account best explains the observations available for that event.

A successful ordinary explanation can sharpen the remaining mystery. It shows which apparently exceptional features are non-discriminating and where better evidence is needed.

9. Several causes may coexist

The simplest account of the whole subject need not be the simplest account of one event.

An archive contains different observation conditions, instruments, histories and experiences. It would be surprising if every report began with the same kind of stimulus. A mixture of causes is therefore a serious model, not an evasive answer.

But a mixture model must still do work. It cannot assign every awkward case to an unspecified “other” category and declare the investigation complete. It should identify which features distinguish the groups and what evidence could move a case between them.

GEIPAN's method preserves distinctions among explained cases, insufficient-information cases and cases unresolved after investigation, with provision for reconsideration. That is a useful model for keeping uncertainty visible while allowing the archive to improve. [12]

A confirmed non-human artefact would transform one part of the enquiry without explaining every anomalous light. A well-supported explanation for many lights would not determine the status of the artefact. Conclusions should travel only as far as the connecting evidence permits.

10. Comparing explanations without flattening them

These are families, not closed boxes. An autonomous machine could belong to a human or extraterrestrial programme. A person could experience altered awareness during an external event. Evidence should establish the combination rather than the combination being assumed from a theory.

The comparison should include failure conditions. What would make a hypothesis less plausible for this case? If no observation could count against it, it may remain a philosophical possibility while offering little help in identifying a target.

11. Why origin does not settle intention

Even if another intelligence were established, “Are they friendly?” would remain a question about particular behaviour and relationships.

Technical superiority does not demonstrate moral wisdom. A gentle encounter does not establish the intentions of every member of a population. An intimidating encounter may reflect hostility, indifference, misunderstanding or the experiencer's interpretation; distinguishing these requires context.

Treat a claimed identity as information to check. A being's statement about its home, authority or purpose is testimony from that being, if the encounter itself is established. It is not automatically an authenticated diplomatic credential.

The same applies to a teaching that assigns intentions to broad groups. It may provide a coherent ethical framework without identifying the agent behind a particular recording. The course's later portraits should retain each source's descriptions rather than converting them into a universal catalogue.

Human responsibility remains central. The possibility of help from elsewhere does not remove the need for clear judgement, consent, accountability and care for the world already shared with other life.

12. What would move the enquiry forward?

The most consequential findings would connect observations that currently sit apart.

An alleged programme could be linked to authenticated records and inspectable material. An exceptional manoeuvre could be supported by synchronised independent measurements. An account of communication could supply verifiable information preserved before feedback. A proposed habitat could yield evidence of actual activity.

These are demanding tasks because the conclusions are demanding. Their difficulty is also what makes named officials' specific claims useful: if they identify actual routes to evidence, those routes can be pursued through appropriate investigation and disclosure.

For discussion:

The first six chapters establish an enquiry with several possible outcomes, including discoveries larger than our present understanding. The next chapter, A worldwide question, examines what different countries have recorded and how national institutions have investigated the subject. It asks whether international evidence strengthens particular connections or reveals different phenomena grouped beneath the same name.
