there are more then 1 race of aliens

Greys - ( they are earthlings but brought from another solar system )( they are at war with the reptilians and draconian) want to become like us, but are really a plant based race, crated by the forerunners to protect their children, the archon

Reptilian - They were brought back from extinction by the archon, but got to powerful and have conquered parts od the globe

Draconian - They control most of the world and are persistent on harvesting human spiritual power ( they are at war with the greys and reptilians )

Archons - They have all died out by the draconian, and their post planet was Madrid, it was between mars and Jupiter where the Astrid belt is

Forerunners - They are the oldest physical race, which defy death, unless they are killed by another

Reedhys - observers of all current events, they were the original race to create the moon , but lost it in the great war, they are waiting for humanity to wake up, as they have always been the servants of the conscious mind
