> When Europeans set sail for the "New World" hundreds of years ago, there was a huge financial incentive. Religion was actually a big reason too. Perhaps in the modern era after the caliphate fails to establish their Islamic kingdom on earth, they will attempt to do it in space. Money is a good reason to temporarily get equipment and people into space, but those people ultimately want to come back home. To get colonists to leave earth forever, raise families while risking life and limb (and their children's life and limb) in a hostile, dangerous environment forever, you'll need more than a paycheck. You have to be fanatically devoted to it. Religion will do it.
