You can't stop people from believing in what they want to believe.
I don't believe in god myself either but I have no problem with the people that does believe in him? Maybe a god did exist but he wouldn't alive now and there's no possible way for a heaven or hell to exist.
You're right I don't believe a god had anything to do with my creation. It was just my parents having sex with each other and my dad's sperm mated with my mom and I was created.
