What would happen to religion if life on other planets were found?

The catholic church would demand baptizing them, and wage war against them. The Islamic faith would demand they worship Allah, and declare a holy war against them.the jews would demand they begin looking for an overdue roman messiah, then forbid their kids to breed with the alien scum. Then us atheists would dance and rejoice (not in god) at the fact that religions have someone else to harass now.
