God creating he universe is also a much more unlikely situation than the big bang happening on it's own, you have to brush aside logic completely to believe in God (likely/unlikely of course has no bearing on what actually happened).
Actually, I have no problem with the Big Bang being the mode of creation.
"Let there be light", boom.
Yep, that works for me.
And I also don't have a problem with evolution being yet another mode of creation.
One that, instead of lasting only seven days, continues indefinitely.
Also, when you study biology, you see some weird jumps from one species to it descendants.
For instance, there is no intermediate structure between hair and feathers.
You have one or the other.
