> The only absolute laws are the laws of physics.

Then you're left with explaining the laws of physics and why they exist. Those laws are contingent after all. See Aquinas's "argument from contingency" (though not the general cosmological argument or Kalām variant, which are not very good) as well as Leibniz:

> I don't know the author, but anyone advocating for a God or a religion is a person 1. with an agenda and 2. can has no scientific basis for his thesis.

There is no scientific basis for Gödel's Incompleteness Theorem either. That doesn't mean it it false.

> God, the one in Quran or Bible, doesn't exist. It's as simple as that.

It is possible to think critically even if you are Catholic. For example, here is a book that goes through some logical arguments for God's existence: https://www.amazon.com/Five-Proofs-Existence-Edward-Feser/dp...

You can listen to Edward Feser on youtube for some the reasoning behind Catholic dogma.
