If there is a creator, so what?

[Mudhammam]

What makes a creator seem probable is the fact that we can't explain a cosmos that always existed.

I forget robs's exact quote but it was something like the following:

Imagining a being who can do impossible things doesn't actually make impossible things possible.

You can pretend the cosmos is "explained" by positing Mind but now you're in the exact same predicament and can say nothing to account for that as you thought needed to be done in the first place. To recognize this would be an important first step in learning how to reason logically.
