I see your topic is influenced by a topic i posted earlier titled "God is dead". Here are a few remarks I have that will probaly clear your misunderstandings with the atheists:
1. The fact the universe does not make sense without a God does not mean there has to be a God. It can exist without making any sense to our human logic, as we are so desperately small, meaningless and insignificant to the Universe.
2. There doesn't have to be a purpose for the universe to exist. It's mind boggling but we have to accept things that don't make sense to our feeble logic. We are nothing more than mould on a ball of dust rotating in space.
If you are able(it's hard) to wrap your head around these notions, you might be able to resolve your personal conflicts with atheism and reality.
