Space, the final frontier; or is it just a waste of time? Are the billions of dollars spent in sending machines and men where no man has gone before justified by any of the knowledge gained so far? Could they be put to better use in other realms of government spending or would it be better for the taxpayers to keep the money? And if such spending is justified, how should space exploration progress? Should it mainly focus on sending robots into space to conduct research? Or do humans offer enough of an advantage to justify the extra expenses in ensuring their safety? Should space agencies mainly focus on exploration or should settlements of some kind be established? And how extensive should those settlements be? Should they be on the level of Antarctican settlements where all the people are temporarily there and then they come home after a summer or a year or two? Or should they be like the settlement of the Americas and Australia where families move there to raise families? And are there other aspects of space exploration worth considering?
If there were settlers in space that could survive without constant shipments of food, air, and water, then they certainly could survive to return to the Earth and fix it up.
Actually, we do know where some minerals are. For example, we know of Helium-3 on the moon and there are plenty of hydocarbons on Titan as well and trillions of tons of minerals on asteroids.
How? There are no known inhabitants on any of the planets other than Earth. They'd have no one to fight against.
There are a lot of technologies first discovered for use in space.
If an asteroid is big enough to destroy the world and cause a huge drop in population, there would be no chance of repopulating. Diseases and starvation would kill the survivors.

None of which we know where it is nor do we have the equipment to do it.

Which would result in a war, just like the pilgrimage.

Such as what? a toothbrush?
