Joz, what you're describing sounds a lot like 'The Chariots of the Gods', and I think there's a lot to it.
The carving of the astronaut, seated before control panels and having breathing tubes going in his nose - that sort of thing.
I have a personal belief that everything we regard as 'modern' existed in the past, and that we are 'replaying' our history - that would explain how the Banksters have been in control for hundreds if not thousands of years - because they had 'prior' historical knowledge, and are merely repeating what was done before to suit their own purposes.
Just a theory of mine.
Getting back to temples and such:
I know I've mentioned it once or twice but this one really sticks in my mind as proof positive that we have been contacted by Aliens, if only in the distant past {or my repeating history theory, whichever}:
There is a temple whose walls were enormous pieces of stone fitted together with laser precision in such a way that they interlocked with each other, the top one fitting perfectly with the one on the bottom and in turn the ones next to them, eliminating the need for mortar or other fastening materials.
The stone slabs are said to be too large to lift, even with modern equipment, and that there are marks along the stone's sides that resemble those made by modern machinery.
AS if that wasn't enough, there's an inscription at the top of the doorway which led into the temple which read something like:
'This is not a temple to a Deity, but a house for a living God'
and there are carvings showing a snake - headed or reptilian life form on the throne.
I wonder if David Icke knows about this?
