Are Grey Aliens Harvesting Human Souls?

One theory is that greys are interested in obtaining human souls, which they believe gives them control over death. By manipulating human DNA, they hope to create their own spirits and escape the destructive force of the material universe.

Genetic manipulation by the Greys has gone on for centuries, but has led to a number of negative consequences, such as violence, greed, and hatred. Racism is said to have been developed as a way of protecting their experiments from contamination by other races.
