LadyLake,
I've had the same thoughts as you regarding the depositing of artifacts in the 'past' for future (our present) people to 'find'. I also think those artifacts such as the Book of Judah contain hidden information within them. Information that only adepts can decipher. The normal lay person reads it and sees only religious doctrines etc, but someone skilled in symbolically hidden cyphers reads it with a whole different awareness and attains completely different information.
I also ponder it they sent 'road maps' back. Not literal road maps but 'tablets of destinies'. 'Follow these events and you are on this timeline'..'follow these events and it will take you to this timeline' etc. 'Do this and a new branch will form'.
Look at the Mayans, their pictures were in overlays, many different outcomes overlaid one on top of the other. The Mayans were also time keepers, so who is to say those pictures didn't represent timeline overlays?
And the Mayans state they had Tall Visitors who taught them about time keeping.
They also have pictures of reptilian beings, whether they actually saw those Beings in reality or were shown pictures of them is another matter.
If they saw them then that means the Reptilian Beings may have played an integral part in the history of this planet.
LadyLake if you are interested in the Mayans there is an interview in May 2008 on CoasttoCoastam with Richard Shafsky. He speaks about things that will rock your boat! If you want a detailed synopsis I can send you one.
Barry, have you seen the Mayan drawings of the reptilian beings ?
If so, may I ask what are your thoughts on them? Could they be one of the races which are considered hostile to humans?
Crowmirror could the scoop marks be used for taking tissue samples for crafting around implants so your own body doesn't expel/reject them?
All the Best
