> In other words, that’s more of a religious rather than scientific hypothesis.

I get what you're getting at, but I don't think it's so clear cut. Religion is more about organizational beliefs than just beliefs. Many parts of science are pretty far fetched in terms of us only knowing a bit with a very tightly constrained perspective (humans sitting on Earth with limited technology in the Solar System in the Milky Way) but making leaping conjectures. So in fact, science and religion have some shared analogues. (C.f. Paul Feyerabend.)

Certainly, the hypothesis you replied to is incredibly far fetched. But I don't think it's religious. It's more fantasy.
