Dealing with an atheist question

Hello Rabbi.
I did not see any explicit reference on the site to the logical refutation, which is perhaps one of the strongest by one of the atheists on the internet. I would be happy to know whether the rabbi finds fault with it.
As is known, the religious claim is that God is an existing entity that does not belong to the concepts of time and space. [Even according to the understandings of the Big Bang theory, time and space were created].
But, as we know, every existing entity is subject to the laws of time and space. In any case, the claim that God is an existing entity that is above time and space is contradictory. It follows that God does not exist.
What does Rabbi Dr. think about this evidence? Can there be an existence for something that cannot be described by the laws of time and space and is not subject to them? The atheistic argument here is based on experience and common sense. While the religious argument is not based at all and seems like far-fetched speculation. Do you have a solution to the argument ?!? Can you demonstrate and bring to our understanding a belief in a being that is not within the boundaries of time and space.
thanks!
