The Reasonableness of Theism/Atheism The discussion of the evidence for the existence of "some" God can go on indefinitely, and we will always be talking about a mere generic concept, not about God itself. However, proof of this God can be obtained by the scientific study of his action in the world, especially by the critical history of miracles and prophecies. That is why I say that the proof of the existence of the true God is a scientific-experimental problem, not a problem of mere logic.
However, the logical reasoning of the “first cause” serves as an excellent auxiliary force for evangelization. First you argue that God exists, then you prove which God is the true one. However, this only works for people who are very sensitive to the logical demonstration cogency.
To the mere metaphysical proof, the scientific-experimental argument must be added. But practically everything in this field has yet to be done.
