The Moon aka The Lunar Station

About 12,500 years ago, we had a completely different moon. Our original moon was the planet Tiamat. Tiamat was a planet where the entire surface was a salt water ocean. It was a very large planet, about 80% of the size of Neptune. It was full of aquatic life, some of which were humanoids. It acted like a giant mirror. The sun reflected off its massive oceans and bounced over to Earth. Tiamat is the reason why we have ancient legends about 2 suns.
