Religion will always be around, dear one. There are two major problems with your question, aside from it being rude.
One, you haven't proved that all religion is entirely organic, bovine-sourced fertilizer.
Two, you haven't shown that atheists are sensible. They're anything BUT sensible. There is no way to know there is no God, much less prove it, so there is no logic, reason, nor evidence to shore up atheism. In spite of that, you blithely pretend there is no God. Don't bother denying it; if you didn't, you would be an honest agnostic. Besides, every year millions of honest, sane, and reasonably intelligent people experience God for themselves. It's not like there's an equal amount of evidence for theism and atheism.
You pretend without any evidence that there is no God. There is evidence for God's existence, and yet you refuse to find out for yourself the single most important thing we can know. You sure have a double standard where evidence is concerned, dear one.
