Barring censorship of my comment, I posted this:
That's a load of codswallop..or should I say, godswallop.
Religion will always exist because belief requires ignorance of the world and laziness, the unwillingness to check facts or to learn. Religion tells the ignorant they have "knowlege" and "wisdom" because they are ignorant, an easy way for leaders to gain followers and pick their pockets while saying it. For the less intelligent and the intellectually lazy, religion is an easy road, so they're willing to take it.
Religion provides a quick path to wealth, social status (e.g. those claiming their "race is superior"), power and position, sex with the unwilling (usually women and children), patriarchy and undeserved privilege. For bigots, sexist morons, racists, the greedy, the selfish, and mass murderers, religion provides justification and the claim of "absolute power". As long as some scumbags want those things, there will be religion.
