Proof of the non-existence of God

Hello Rabbi, I recently came across the proof of the non-existence of God. I would be happy to hear your opinion on it, whether you find it contradictory, and what it is.

Axioms:
1. God is perfect in all perfections – eternally existing in time, and infinite in space.
2. God is part of the cosmos, where the cosmos is “everything that exists, has existed, will exist.”
Now there are four possible existences for the cosmos we are in.
1. The cosmos is eternal in time
2. The cosmos is not eternal in time
3. The cosmos is not infinite in space
4. The cosmos is infinite in space.
Now we see, according to every method and according to “Ockham’s Razor,” that there is no need for G-d.
1. If the cosmos is eternal in time, then it is its own cause and therefore there is no need to add God.
2. If the cosmos is not eternal in time, this means that God is not eternal, and then we have ruled out God because part of His perfection is to exist forever.
3. If the cosmos is not infinite in space, then God is not infinite, and this contradicts the definition of His perfection.
4. If the cosmos is infinite in space and God is also infinite in space, there can be nothing but God, and therefore I cannot exist, and the very fact that I exist means that there is no God.
