Alien abductees say that part of the Alien abduction agenda is to create Alien-human hybrids. People claim to have had genetic material harvested from them and even to have seen their offspring created by the aliens. The hybrids have a range of appearances from some that resemble Grey aliens with human-like features all the way to humans with slightly large eyes. These hybrid children can often be quite beautiful. Most have hair on their heads, human skin, slightly large heads with slightly large eyes.
There are several theories as to why the aliens are doing this. Many people believe they are benevolently trying to advance humanity while other people think that they are creating a race to take over the world.
