Statement
International legitimacy for settling or biologically seeding a world with credible indigenous life is unresolved.
Evidence dimensions
- Basis
- normative
- Readiness
- no known path
- Confidence
- supported
Assessment rationale
The Outer Space Treaty assigns state responsibility, due regard, consultation, and harmful-contamination duties, while COSPAR supplies scientific contamination policy for Solar System missions. Neither source creates a legitimate international authorization process for settling or intentionally seeding an extrasolar world with credible indigenous life; future-generation principles add interests but not a decision authority.

Assumptions and limits
The assessment applies to this bounded statement and the cited source scopes. A source can support one relationship without validating a generation ship, and an editorial grade does not substitute for independent review or representative demonstration.
What would change this conclusion?
A widely ratified instrument or comparably legitimate international process would need to define representation, evidence thresholds, indigenous-life presumptions, contamination and noninterference duties, future-generation standing, enforcement, review, liability, and irreversible no-go decisions. A sponsor or launch state acting alone would not resolve legitimacy.

- Conflicts: A generation-ship organization could gain influence from defining legitimacy rules; any framework must therefore be independently governed, internationally participatory, scientifically revisable, and able to deny or revoke a mission.
