Telegraph | News | Hawking: Man must leave planet Earth: "The long-term survival of the human race is at risk as long as it is confined to a single planet,' he said. 'Sooner or later, disasters such as an asteroid collision or nuclear war could wipe us all out. But once we spread out into space and establish independent colonies, our future should be safe. "

Of course, because our times are in God's hands [Ps 31:15], there is a problem with seeking to predestinate the future. The problem is this: God is a jealous God and will not give His glory to another. Those who seek safety in their own schemes make God their enemy. The reason is this, He knows that He is God and that we are creatures. There is no safety outside of Him, the true and living God, and it would be a most unloving thing for Him to do to pretend that this isn't so. Ps 9:20 Put them in fear, O LORD: that the nations may know themselves to be but men. Selah.

Men tried this once at the Tower of Babel, which modern "science" deems a myth. See Genesis 11. [For those who attended public schools, that's in the Bible.]
