It strikes me that it is impossible to prove that God created the heavens and the earth and all that is therein. Proving a thing is to remove all doubt.
I can prove that a loaded gun can kill an animal by actually using it to kill any animal. The claim can be tested.
I cannot call God to a particular place & time and have Him demonstrate another creation.
Therefore, the best I can accomplish is to compile the available secondary/tertiary evidence that speaks logically to the claim that God created. That is not to say that such evidence is not very strong.
That is true, also, about any other claim to explain origins.
Whichever way one turns, one is left with compiling evidence that speaks to one’s claim.
And at some level, that involves the faith to continue searching. It is, therefore, a belief system.
You can’t prove evolution either. Both deal with the unobservable, unrepeatable past. They are historical sciences, and historical sciences depend on “multiple competing hypothesis.” And from my stand point, the argument from Creation/ID wins the competition hands down.
Thank you for sharing your insights and testimony, dear brother in Christ!
