Only the fool says there is no God.
The crux (pardon the pun) of the matter is not “Belief” in the existence of God, with or without “mathematical proofs”, but rather in individual, personal acknowledgement of His Lordship.
Satan & his demons all know that God exists; their problem lies in their rebellion and refusal to submit to His Lordship... for the time being.
Carl Sagan believed scientists would eventually find proof of God...
Reminds me of Douglas Adams’ story of the Babelfish..
St. Thomas Aquinas did the same thing in the 13th Century without computers.
Just as Neals Bohr, the Dutch atomic physicist discovered with electrons, so is the perception of God.
When an electron moves from an outer orbital to an inner orbital it gives off energy and a photon(light). The same thing is true when you go within to perceive God. A higher level of consciousness is always perceived as light from a lower level. Thus... God is Light!
We exist within God, and therefor are also a part of God, just that we are still asleep.

I have faith - don’t need test tubes and slide rules for that...
