Will religion ever go away?

I wonder if mankind, on a global scale, will ever denounce religion? What would it take to do this?
Do we really need to wait until space aliens arrive for all these insane people to realize that religion is just a made up story, and done in many many different ways and in different languages, but the fantasy is all the same.. One guy that is God and all his disciples.
Humans devote way too much time to this fantasy.
The only good thing about religion is that it does give people something to focus on rather than fall into despair. They can actually believe someone loves them, even if said person never shows themselves. Kind of like an internet romance, except the other end is just a picture and never replies.
