So cool ancient Egyptians made jewelry with glass made in the desert by meteoroid air bursts.
King Tut was buried with a dagger made from a meteorite.
Meteorites also bring new life including viruses. Although there is debate weather or not a virus is life.
And I just figured out on my own that UFOs are the shape they are so they can 'slide' down the gravity they're bending in front (or behind) the ship. Like a big tic tac or saucer going down a water slide. Because I imagine bent gravity makes a shape, so make a ship shaped to match the bent gravity shape.
And then there's Oumuamua.
