What I've got is a pack of playing cards. In this pack there are a trillion trillion different suits, and each suit has a trillion trillion different cards, or perhaps more.
And I ask you to pick one of the cards and tell me which card it is.
You tell me it's the ace of spades (ie, you're saying God created the universe), the chances you are right is so small.
But here's what I've got.
If the universe is so complex it has to have been created by a being or god of some sort, then this being or god has to have been created by something, which in turn has to have been created by something, which in turn has to have been created by something. So, you can keep going back as far as you like. The logic that the universe was created by somebody or something doesn't wash.
If the universe couldn't have created itself, then the god who created the universe couldn't have created itself, and whoever created that god couldn't have created itself either.
So, you're really at a dead end.
