And as for Hawking's absurd notion that we must leave Earth in order to survive,
Not as absurd as Hawking's notion that any ETs who discovered us would be like the Europeans to the Indians. The Indians had things the Europeans wanted. On our planet's surface, what could we possibly have that ETs would want and couldn't get more easily elsewhere? They wouldn't be able to eat us, or eat anything that grows here, or have sex with us. Using us as slaves would be too much trouble, we'd need special life-support systems to live in their atmosphere. Any ET civilization capable of getting here is capable of mining asteroids for minerals and has no need of ours. They would need to . . . xenoform the Earth before they use it as shirtsleeve living space, and that's cost-prohibitive and takes centuries, if it's anything like terraforming.
