Physics and God

Hello, Your Honor, I have a question:
Let's assume that the universe began from the singular point, as atheists believe, the singular point must be in a certain motion, because if it is not in motion, it will not trigger any reaction, and then there is no universe and no explosion. Therefore, two options arise, either there was a point, and it was always in motion like a loop, or there is a God. But the first option can be ruled out, because matter that is always in motion, has always been in motion, so it could explode at any moment on the infinite timeline, and not necessarily at a specific point in time. And this proves that the point or what created the universe has the right to choose in a certain sense, because it decided that at this particular time an explosive reaction would occur, because since it has no beginning and no end, it could explode at any possible timeline.
The question is, is there something I'm missing, or have I misunderstood? How come science hasn't fully figured this out yet…?
