I could never claim to explain the entire universe. Bits and pieces are all I can hope for, but I'll get as many as I can. I think we disagree over the purpose of religion. You seem to think that the purpose of religion should be happiness and contentment, independent of truth. I personally want truth, or at least as close to it as we can come.
Religion is a reliable source of happiness, true.
But it is an unreliable source of facts, which are what I value most. God not required for anything.
