That doesn't preclude the possibility of there being another similar being that didn't create anything or interfere with anything yet still exists though, does it?

If God created everything there can't be another being that didn't create anything because God would have had to create him first.

Did God create himself? Or did he already exist? If he did, what is time? Is time a cycle, or a line?
