The Morton Theory is a string of theories, that suggest that the alien spacecraft seen today around the world, may not be of an extraterrestrial nature.

WHEN: when they arrived.

and he even gives us the 

WHY: Why they are here and what it is that he believes we as a species must do before contact can be made.
