Why Do We Want Humans to Be Living in Space?

NASA found a series of deep pits or moon caves that hover at a constant temperature of 63 degrees Fahrenheit, which means there's a real possibility that the first permanent settlers on the moon could be cavemen. A lunar base inside a cave would be able to stay warmer during lunar night. You're also shielded from cosmic rays and solar rays. But at the end of the day, it's also worth asking... why? Given that we still only know just a tiny sliver of the risks of being far from Earth for a long period of time,. Why do we want humans to be living in space to begin with? The million dollar answer after the break.
