I just want to interject here and say you're all understanding Occam's Razor wrong. "The simplest solution is the best" is NOT Occam's razor, that's just lazy. No, the Razor is about making as few assumptions as possible.
God creating everything is simpler to grasp and to understand, but makes many grand assumptions (namely, that God exists, that God cares about us, and that God is omnipotent)
The Big Bang (or whatever other geneis theory you have) makes fewer assumptions because almost all aspects of the theory has scientific backing, so it's not about assumptions, it's about following the evidence.
Occam's Razor is a principle that generally recommends, when faced with competing hypotheses that are equal in other respects, selecting the one that makes the fewest new assumptions.
Educate yourself before looking like a tool. Wikipedia (and Google) are both right at your fingertips.
I got it all, baby!
