Super Universe
Defender of God
The most convincing argument against the existence of God (excluding deistic god concepts) that I can think of is the existence of pastors, priests, popes, scribes, and missionaries. No one learns about God directly from God, but instead, it has to come through intermediaries. Why would an omnipotent god who wants a "relationship" with humans never talk to them directly and only speak through intermediaries? Why would he wait for missionaries to tell people about his existence instead of revealing himself directly to them? Why would he need humans to write his "word" for him? He wouldn't. A real god wouldn't need intermediaries to speak to people (one of the most inefficient and unconvincing methods possible), he'd do it himself. The fact that humans are necessary to spread the knowledge of gods is very strong evidence that the gods don't exist, and in fact, are human-made constructs.
No one learns about God directly from God but it has to come through intermediaries? The intermediaries claim that only they can interpret the religious books because they need you to obey them and give them money. God never appointed any of them.
Why would God not reveal Himself to the people directly? Because that would violate the reason for the universe to exist. God wants free will, not children who know they are being watched by a strict parent.
Why would God need humans to write His word for Him? God doesn't need humans. A very large asteroid could destroy the earth tomorrow and the universe would go on normally. Some humans wrote books and claimed they were from God.
Humans spreading what they think is God's word is just humans doing what humans do. They want everyone to be like them. They don't like it when others are different.
