Water molecules on Asteroids also supports the fact that the Asteroid belt was once a planet with water that our ancestors lived on

This for me, is just further evidence of the planet some call Maldek, a piece of which hit the earth about 65 million years ago which killed most of the larger dinosaurs and also likely means that about 65 million years ago the nuclear war of our ancestors on Maldek destroyed the planet. The Soviets were the first to discover that the Asteroid belt was a planet destroyed by nuclear weapons during the 1970s when they sent a space probe there.

However, Earth's religions repressed this information in the 1970s because it didn't agree with their holy books.

For example, what if Noah's Ark was actually a space Craft from Maldek that landed on earth with many of the species of animals from that planet? 

This is another possibility that Noah's Ark was not a water ship but a space ship full of either animals or their Sperm and ovums in order to rebuild their offspring here on earth at a later date. 

Technologically, in order to keep Cosmic Rays from killing all the sperms and ovums one would have to put them all in lead lined containers to keep the Cosmic Rays from killing them while traveling between planets. Then they would have to be gestated somehow here on earth in some kinds of artificial wombs. This might be one way to avoid the sterilization that happens to all human beings otherwise who travel into space. It doesn't stop sex but it does stop permanently reproduction at least among mammals like Humans and other mammals.
