This is a fascinating topic, some nice links there, although why are "conspiracy" sites always so messy and hard to read? /rant off
It's fairly simple i think, and i'll present how i understand what's happening. I don't have evidence, just a whole bunch of ideas worked out over
time. I use the bible as reference for a lot of ideas, since it hasn't been proven wrong yet, at least not really with historical timelines and
information, and curiously is very well supported in this field. I've read Von Daniken et al, and as much as i like their ideas, they don't really
dovetail with ALL the evidence, only some.
So the story starts with Adam and Eve, and the fall from the garden of eden. They bred, and had lots of children and grandchildren. We're told that
certain angels saw the daughters of men and came down to join the party, these were "giants and men of great renown". Evidence of their exploits
exists mostly in south america, where giant human remains have been found, and a lot of pyramids, and some astonishing jewellery and metalwork. They
liked to fight and kill though, and i don't think they were really welcome anywhere.
The great flood was partly to eliminate these giants, who clearly had roamed the whole earth by this time. Legend says that these giants are those who
became "evil spirits" tied to the earth. The bible concurs with this theory, and adds that re-incarnation does not exist, and dead people are not
able to float around. The conclusion is that all ghost activity, including mediums and the paranormal, is attributable to these giants, who are now
disenfranchised spirits tied to the earth.
The next part of the story involves queen semiramis and nimrod, her son and lover, who was killed by Ham, the son of Noah for his "wickedness" (it
is said that nimrod's birthday is the 25th December), and his body was cut up and scattered. Semiramis had the pieces of his body collected, but did
not find his penis. She rebuilt that with clay (or stones), and is the source of ALL "obelisks" today. When he died, she told the people that he was
now the sun, and that is where sun worship originated. Nimrod has also been ascribed as the builder of the tower of Babel, as babel was his capital. I
personally believe that from that point on, where the nations were scattered in 70 tribes worldwide, with each tribe having been granted their own
land, that these old stories of semiramis, nimrod, the sun, re-incarnation, father mother son theology, and quite a bit more became fixed in human
lore.
The bible agrees with this version of events, although it is curious that only the jewish history stands aside from the rest in regards to what was
happening. Despite them sounding very progressive, they were fond of child sacrifices, usually burning the children in a gold brazier. The hebrew God
clearly disapproved of this.
Nimrod was also know as the great opposer, and it isn't really clear what he opposed, unless you accept the biblical narrative that he opposed God,
and history agrees with that. He was the first leader of humans, who started most royal lineages and traditions, was a bloodthirsty killer and clearly
saw himself as greater than other men.
Okay.
These "evil spirits" clearly haven't gone anywhere, making them not extra terrestrials, but earth bound, as we are. The beliefs system hasn't
changed since then much either, with ALL religions tying up at that point of the tower of babel. The greatest unknown to me, is exactly how the
leadership and the "other side" tie up, the best answer i have is "satanism", but basically blood sacrifices and such. Most of humanity has
believed that sacrifices affect the world, the bigger the sacrifice the more likely it is to work. I've never tried that, and certainly won't, but
the evidence suggests that there is a kickback from well made sacrifices to gods who have been around for millenia. Pan is one, the cloven footed pipe
player. (as an aside, hymn to Pan was written by Crowley, who clearly believed in the power of doing so. Since then, he's had thousands of otherwise
really smart and influential men follow his beliefs, i don't see the value, but i'm not wealthy or famous???).
So you have "evil spirits" who have their power over matter increased by interactions from humans. Curioser and curioser. These stories haven't
changed, but the UFO's are only a new aspect to an age old problem we humans have. No doubt the "evil spirits" and the "leaders" are working
together for various purposes which are, by their nature evil deeds, against the most of us humans. The bible is very easy to dismiss, until you find
this kind of confirmation coming from the "enemies" of the bible. They believe in it more than any christian, christians have faith, but these
"evil people" are very very sure of the true history, and purpose of specifically Jesus, the teachings in the bible, and the "laws" which have
been laid down for us.
