What do you mean when you say "we need to find him or we dont want to find"? I don't think I "need" to find God. It's also not that I don't want to find God; if God really did exist, I'd want to know. The fact that I don't go looking for him is because I don't want to waste my time, not that I'm afraid of what I'll find.
I don't think that the existence of God has any bearing on ethics and morality. If God is the source of morality and it doesn't come from some external standard of right and wrong, then morality is arbitrary and therefore not "moral" at all.
Also, regardless of whether God exists, it's not like we're free to choose whatever morality we want; our moral judgement is shaped by all sorts of factors, such as genetics, upbringing, and our shared experiences.
I think you're implying that lack of belief in God will result in suffering. But in general, the more religious a society is, the more suffering it has. Why is this?
