Humans have between 1.75 and 3.25 (arguable) billion years left before earth is uninhabitable. That's a long time. We'll go conservative and assume that humankind has up to a billion years before his time is up.
That's a long time. In that time, I do believe that mankind will give up on God and Jesus and Mohammad.
It wouldn't surprise me if man picks up some completely different radical practices in that time, but I think most all of religion as something organized will disappear.
It may seem impossible now, but two factors will work against religion: the wasted resources and time for religion and the education of the population. Some taxing authority will end religion's tax-free status and it will spread. Eventually, everyone will be able to google without typing a keyboard- we are almost there now. They will figure out that religion is a scandal.
