Human-seeding stories are not evidence of real origins

Do recurring human-seeding stories in Battlestar Galactica and Star Trek reveal a literal truth about humanity's origins?

No. Battlestar Galactica's cycle is a theme, and Star Trek's precursor seeding is a storytelling device rather than historical evidence.

Shared science-fiction motifs do not show that humanity was settled from elsewhere. Battlestar Galactica's recurring cycle is a thematic choice rather than a historical claim. Star Trek's ancient precursor explanation supplies a storytelling reason for many aliens sharing a humanoid form. A further reference to an evolved dinosaur species reinforces that these are fictional premises assembled for narrative and production needs. Resemblance between myths or fictional settings is not evidence for human origins by itself.
