Georges Lemaître, the priest and scientist who originated the big bang theory, said himself that the big bang may not be the beginning, but may instead represent a reset of the physical clock which hides evidence of anything before from us. Lemaître even warned his pope not to draw any conclusions about God from the theory.
So unfortunately your OP was disproved long ago by a very famous Catholic priest.
Right on time after the Moderator warning to jump into the fray.
I see some programs of Science narrated by a wonderful black 60 and so years old narrator.
And they say that the beginning of the Universe could have been the end of a previous Universes. That you cannot go from Universe to Universe. That each black hole is and end of part of the Universe but Hawkings defends that could also be the reverse, the beginning of one.
Another was saying that our Universe was created to go forward in time, so maybe there was another Universe going backwards in time to balance.
For me, Big Bang was wonderful. God created the world with the Big Bang. But, as we learnt in the past. let us not put much faith on nature and science, for what it is today, may not be tomorrow. If today the sun gyrates around the Earth, tomorrow it may be the contrary.
So, let is keep Faith where Faith is. Faith is believing without seeing: Watch out, Thomas, they who did not see and believed are the happy ones.
Trying to scientifically prove God is an impossible task.
But knowing by Belief and Faith is of no less value as Scientifically proofs.
That God is the Supreme Creator is said in the Creed: “Creator of Heaven and Earth”. Let us enjoy the modern gospel writers, the scientists, who are trying to discover the mind of God, and let’s enjoy the beauty of the Universe as a pale image of the beauty of God.
