The fuck are you even talking about, not having an answer for something makes it a religion? How stupid are you, really? It's the best we have, the big bang theory, thanks to a lot of evidence that indicates it did happen. Scientists don't know for sure and they don't know many things but it definitely doesn't make it a religion. What religions do is: I don't know something, instead of admitting it, I will make something up to explain it.
