God's existence--A different approach

Because it exists. Sheer randomness can not create the sort of rigid and strictly enforced structure that is our reality.



Cause and effect, again, too structured to be chance. An intelligence had to create such a framework. It's improbable that our entire reality is the single instance, even within itself, of such complexity just appearing naturally.

You are assuming an awful lot about whatever is outside our reality.
In fact, you're assuming it's exactly like our universe, with causality and entropy, randomness and order, intelligence and intent... none of which is necessarily so. We have no way of knowing anything about it, except for the one relevant fact (well, more like hypthesis): something in it or about it caused our universe to come into being.
