Why would this explanation be needed by creationist?
If a creationist can simply conclude that god didn't need a creator, why can't you do the same for the universe itself? It is inconsistent to say the universe is too complicated to have formed on its own but then say that god (an even more complex "thing") doesn't need a creator.
We have to start somewhere, evolution doesnt start at the beginning does it? Why is it ok for one not to go into the more complex things (how did life get here) and yet not ok for the other (how did God get here)? bare with me, I'm just asking questions as they arise.
I'm not sure I understand your question. Sure, you can explore "how God got here" but God by definition doesn't have a beginning, right? I agree that something had to be here at "the beginning" that wasn't created, otherwise you'd have a problem with infinite causality. But it makes more sense to me that something infinitely simple has always been instead of something infinitely complex.
