One of the problems I have with theism is the argument that nothing can exist without being created, so therefore there must be a God, who wasn't created, who created everything else.

You're thinking of God as if existence were simply one of His properties. But He IS existence. His very nature is to be: "I am who am". It is impossible for Him not to exist, for then existence itself would not exist.

Or man made up God to explain scary lightning and why people die.

I find my version much more reasonable than yours.

But don't let me stop you from believing whatever you want to believe.
