Well, the Big Bang theory was originally based on the observed motion of galaxies, no matter what justifications it was later given. And, since that time, it's been shown to be consistent with further observation and evidence, so the theory's origins are irrelevant.

Saying it's not true because of it's origins is like saying, "The Nazis invented Volkswagon, so riding in one of their cars is evil!"
