Fk, I wanna join to the discussion, but my english is poor :S, I can answer why does I think that the "god" idea/concept is ridiculous.
PD: 60% of people who thinks that god doesn't exists thinks that they are god, is a "delusion of grandeur", those who thinks that they are god sometimes are really smart people, with an I.Q over 120. Those who said: "God doesn't exists" before I joined to this topic, please, tell me if you think that you are god.
It's scientific.
