pleidians are described in history long time ago.
That race is not interested in abducting us, thats another race, which i think is in extinction.
Those pleidians are reported to some UFO encounters.but do not want contact with us, they aren just studying the ground, plants and other biological things.

Also they are what i would call, sons of GOD, they are the people that did teach to humans what is religion and how to follow god rules and love to keep homo sapiens alive. They told us about GoD, but of course the thing is so much more complex that human mind would't understand on that time, so they have to tell the story in another more understandable way. Which is bible.

Aliens are Connect to JESUS and GOD and Virgin Maria in some extend.

For example. Some UFO Spacecrafts are the ORBS or Spheres of light.
In mexico one of them did fall and a woman built her own museum ( victoria museum of OVNI (UFO in spanish)). And she has on of those little globes, and for her surprise, those globes are exctly the same, painted in some pre renascentist pictures.

Where GOD stands with moses touching that globe with some antenas and jesus with his feet on it.

Also in 2012 the magnetic shield of earth will fade away, and will expose us to radiation, deadly.. and they come to help people who believe in love, because those are the ones to keep life with meaning. and not the war ones, that lead to destruction all over.
