So if you "don't know" how do you "know" somebody else is wrong? You don't even have an answer yourself. That sounds like what the Hip Hop world calls "hatin".
You don't know how the big bang started yet accept it as a logical explanation for the existence of the universe?
And of course none of that is faith based.
Do you realize how hypocritical you sound right now?
EVIDENCE.
If the religious claims are true, where is their evidence? Saying god did it doesn't answer anything because all you'll do is then ask HOW god did it.
Even still...I didn't say religious claims were wrong. I'm saying that there is NOTHING to support them. There is more evidence to one claim than the other...and more evidence gets added daily.
The universe is expanding via something called what we call a red-shift and is explainable via the doppler shift and was observed by the edwin hubble in the 1920s.
Add in some details about what we know about sub-atomic particles and nucleosynthesis in stars then the current thinking is what resembles the Big Bang.
What the fukk are you asking at this point?
