There are at least dozen ETs that visited our Planet in the last 100 years and at least 50 in the last 10 000 years

The Extra Terrestrial life in our Galaxy is grouped into alliances.

The ever famous PLEIADIANS are one such alliance group, only one problem, they actually call themselves Plejorans (or something to that effect) and live beyond the Pleiadian stars, not that it matters really.

The ET alliances have very large philosophical differences between them, The Pleiadians for example are what we would call more benevolent and believe in "service to others" way of life. They also happen to be very advanced.

Another group is the ORION Group, now this is important, please pay attention, these guys are the bad a$$es.

The Orions are believers in Fascism, the totalitarian way of life. We here on Earth have been very unlucky bunch of humans, The Orions got to us first, Orion group came to us in our ancient past, and they stayed with us, they infiltrated us, shaped our beliefs, our cultures, messed with our DNA, and so on.

The Greys, are part of the Orion group, it just so happens that different kinds of Reptilians are part of the Orions.

If you look at present day US/NATO/CHINA/RUSSIA/ISRAEL world war 1, world war 2, coming world war 3

These are all results of the Orions.
