The proof of the existence of God is basically on the entire creation. Everything which is existing is existing because there is a Creator who created them. The creation which we see in it vast majority can't just have come into being without a Creator. There is a God who is the creator of the entire universe.
Several people have been arguing about the existence of God. God exists. He is the one who created the heavens and the earth. He is the one who brought the entire universe into existence. He made everything and only He himself does not have a beginning. He is the God of all creation.
Our God is the Greatest among all that exists. He is the biggest among all that is big. He is wiser than the wisest. Our God is a holy God. Our God is the strongest. He is God. Everyone must accept this reality. He is God.
If you are rich, he made us rich. If you are in power, he gives you the power. The live we all live, it He who gives us. Our God is a great God.
