Once we get a lot of experience flying back and forth to the Moon, we’ll develop ships that can fly out to the asteroids and we can mine any material we need from there and fly back and glode down and land on the ocean.
We can use the Helium3 that is common on the surface of the moon, and uncommon anywhere on earth, as fuel for our nuclear reactors. We’ll use both fission and fusion reactors in our energy industry and our transmutation of elements science and technology.
Once you investigate and discover how life exists on earth, you realize that it must be fairly common throughout the universe. Life naturally evolves whereever the right conditions exist. Life is a feature of the chemistry of the universe.
