Am I a Deist? Cosmological Argument seems reasonable to me.

Okay. So something in another reality caused our reality, because things need a cause.

Where did that reality come from? It must have been caused by something in yet another reality, because everything needs a cause.

And so on. This is fine of course, there's no logical problem with infinite regression. But that's all you get until you just break your own rule. If you're going to do that, it's not a rule at all. You can't even apply it to our reality. If there are exceptions, it could be one of them.
