There are 5 proofs of the existence of God. It is written by Aquinas. I give it below:

1. Proof through motion means that everything moving has ever been triggered by something else, which in turn was triggered by the third. It is God that is the root cause of the whole movement.

2. Proof through the generating cause - this proof is similar to the first. Since nothing can produce itself, then there is something that is the root cause of everything - it is God.

3. Proof through necessity — every thing has the possibility of both its potential and real being. If we assume that all things are in potency, then nothing would arise. There must be something that contributed to the transfer of things from the potential to the current state. This is something - God.

4. Proof of the degrees of being - people talk about the various degrees of perfection of an object only through comparisons with the most perfect. This means that there is the most beautiful, the most noble, the best - that is God.

5. Proof through target cause. In the world of rational and unreasonable creatures, the expediency of activity is observed, which means that there is a rational being who sets a goal for everything that exists in the world - this being we call God
