If god created the universe, and everything that will happen is determinated by laws of nature if god DOESN'T influence in the universe, all influence by god would mean that god changed his opinion because he could have made the beginning state and the natural laws just as he want, because he is allmighty, but if god is perfect, he won't change his opinion, because there can only be ONE perfect opinion and one of the two opinions would be wrong. That means 1. God doesn't exist OR 2. God does not influence in the universe OR 3. God is not perfect. Each case would mean that there is no reason to pray to god.
