The “laws of physics” are just observed possibilities and impossibilities being expressed physically. They are not the origin. They are the observed expression of the origin. The origin remains a total mystery.
OK, but that's a trivial observation with which no critical thinker has disagreed. We don't know exactly what that which began expanding most of fourteen billion years ago was, why it happened then, or why symmetry among the forces broke as it did. Those questions have no answer at this time and perhaps never will, and need none. We can begin with what we do know and deduce conditions and events back to a hot, dense, and otherwise seemingly featureless starting point and describe its subsequent evolution as well as how that world works today.
So far as we can know, or even imagine, this is the only universe that is possible.
My imagination is better than that, and yours probably is, too. I just shared some of those imaginings with you earlier today
here.
The degree of intelligence required to generate even this possibility, let alone others, is far, far beyond our comprehension..
What seems to be beyond your comprehension is that intelligence might not have been involved.
You assume that you need evidence for everything. You don't.
If he's a critical thinker and an empiricist, and it appears that he is, then he needs sufficient evidence to justify belief according to the laws of reason and of evaluating evidence before believing. If he were willing to believe with less, then he would be a faith-based thinker. We all started out like that, and many people can and do still think that way, but for others, after learning what the power of the one form of thinking is and what the risk of the other is, that has become impossible. Such a person DOES need sufficient evidence to believe.
that is you eliminating the evidence that suggest that there might be intelligence.
Whatever you are citing as evidence for intelligent design is also evidence for a naturalistically arising universe, which is a better hypothesis if neither can be ruled in or out, because it's simpler. It only requires that nature and its laws exist. Creationism requires both nature and the supernatural to exist.
