In the case of logic, aren't you a complex being? You can manipulate matter in such a way that you can make a simple plastic bottle, or something as complex as a computer processor by manipulating pre-existing matter.
We look at God the exact same way, manipulating pre-existing matter (the elements making up the "infinitely-existing" universe) and making stars, planets, and humans.
Now, that isn't scientifically provable, but its where we get our logical conclusion, at least. You can say a pink unicorn manipulated matter, or the FSM was drunk in space flinging pasta everywhere (lol), but it doesn't affect the logic, and doesn't prove the hypothesis.
I am not looking to prove God did it because I cannot. If God or the FSM exists, only He/it can furnish proof if its existence since it cannot be proven/disproven using science.
