“Well, you have the same problem with God. Who created God?”
No, that’s a misconception. A god that is created is not a “big G God”, but a “little g god”. The theistic conception of divinity requires the divinity to be uncreated and eternal, or it is not a divinity at all.
If you want to talk about gods that need to be created, you should seek out some polytheistic pagans to debate that with.
