Supporting citation for public claim

Many ancient calendar systems required sustained unaided-eye observation, rule-based computation, and institutional continuity rather than modern astrophysics.

Answer / theory: Many required careful unaided-eye observation and mathematical schemes, but not modern astrophysics. What supports it: Egyptian, Babylonian, and Maya evidence shows long-term observation and rule-based timekeeping. What is weak or disputed: Claims of impossible precision often ignore cumulative observation over generations. Evidence level: Strong Evidence for sophisticated ancient astronomy; Weak Evidence for impossible knowledge.

Limiting / critical citation for public claim

Cataloged Egyptian, Babylonian, and Maya calendar records do not establish a single hidden global science inherited from a lost civilization.

The evidence does not automatically support broader causal, technological, transmission, or literalizing claims beyond the cited record.
