That's a false equivalence. You can observe the phenomena that I briefly touched on for yourself, crunch the numbers, see the results. Data, evidence, observations...these will always trump claims about Gods and Goddesses without the same amount of presentable, testable evidence.

Then you get into the God of the Gaps argument, which, as I've said, probably isn't something you want to actually make. It's a really damning sort of position to take, seeing that as the gaps are filled, it leaves less and less space for the "god".

But is the Big Bang not just a theory? Things are left as theories until proved through experiments...I think.

Indeed though, Science fills tons of those gaps. But true origin is still left unexplained and probably can't be explained.
