It doesn’t matter which God, so for argument’s sake let’s say he is Jehovah, Yahweh, the Holy Father - the God of the Bible and of the Christian faith. Of the hundreds of religions followed around the world, it just so happens that the Christians were right after all. God exists, and he is all-powerful and all-knowing. Therefore, he should be praised and worshipped and prayed to, for he made the Earth and everyone on it, so on and so forth.
