I don't think there's any relation.
As for if I believe in God, kind of. Lemme explain.
I believe that there is some God-like entity out there somewhere, but I don't believe in any religion, least of all those religions which bash other religions and discriminate. I mean, sure there are many good things we can learn from religion (I was raised as a Hindu, and there are a lot of stories and tales from which you can learn a lot of life lessons) but that's no reason to literally start killing people because they don't believe in the same thing.
So, basically, I don't believe in creationism and I'm all for science and The Big Bang Theory and stuff. But here's my theory/belief: According to the Big Bang Theory, the entire universe was like a dense structure and then there was a Big Bang and everything started expanding, right? But what created (Idk if that's the word I'm looking for) this dense structure? My belief is that some God-like entity may have created it.
Another theory I believe is that God, or any equivalent to God, is kinda like Schrödinger's cat. God is neither real nor unreal until we can see God. Does that make any sense?
But then again, I try not to get too engrossed in these subjects, cuz like it or not, we're probably not gonna get an answer to whether there is a God or not in our lifetime. Of course we should continue research and stuff about the creation of the universe, but there's no point in common people like us to be arguing about this kinda stuff.
