When The World Began Part 1

   In the first video, settlers from Europe wanted to know how the Native Americans came to North America. This could relate to the fictional story of Superman. He came from Krypton, an unknown planet that's galaxies away. When he came, people from his story wanted to know who was he. They tried to figure out where he came from and what was his origin. They even tried to find his planet, realizing that it was destroyed. They started wondering and later realizing that Earth wasn't the only planet with life. They figured out that there's such thing as aliens. They just don't know how.
