"However, no matter what "scientific" theory you look at, eventually you get back to something that can't be explained without creation."
No you don't.
"The big bang theory starts with the notion of a cosmic explosion that caused matter to be hurled in all directions."
No it doesn't. The Big Bang has nothing to do with evolution.
" So then, under this theory, the question becomes how did the original matter come into existence?"
It's not possible to know. Scientists are humble enough to say they simply don't know.

At least they know when God has them beat!
Actually, that's the part of it we do know. The starting energy of the Big Bang was zero, and has never changed since. The gravitational fields of the universe have negative energy, just as the matter has positive energy, and as far as we can measure, their sums cancel to many decimal places.
