Basic questions about the fundamental premises of Rabbinic Judaism

I came across your answer regarding the complexity of the universe and the necessity of a divine existence that would create existence, and I would be happy if you expanded on it a little.
1:Who determined that every creation must have a creator?
2: Who said that the creator (if he exists) cares about the existence of humans?
3: Who said that we as humans are capable of communicating with a creative entity that is not defined by the same material? (Empirical)
4: How can we know that the same God has contacted humans?
5: If God contacted humans, how would we know which god he was talking about? As we know, there are thousands of gods.
6: If we assume that this is the Jewish God, how would you prove the existence of the Torah-giving status?
7: If you prove the existence of the giving of the Torah, how will you prove the claim that Moses is a messenger of God if God did not Himself tell the people of Israel that Moses is a messenger?
8: If you prove that Moses was His messenger, how will you prove that the Torah has not been distorted throughout the generations?
9: If you have proven everything so far, how will you bridge the gap between God’s will and man’s will?
10: If God is the absolute definition of good and evil, why do you expect humans to worship the same God who has an unknown definition of good and evil that is completely different from humans’ definition?
11: If God is the creator of everything and He Himself is everything, then how do concepts of good and evil even exist in an absolute way?
