They say that extraordinary claims required extraordinary evidence and in that regard I believe those who read the succession of posts that will follow on the WANA Hypothesis will be well served. "WANA" stands for "We Are Not Alone" and is the only name that I could think of capable of distilling the essence of what you are about to see. This is not going to be easy for some to look at since the implications are likely to keep you awake at night.
I am going to initially sketch the theory out in the broadest way I can think of by relying extensively on the photographic evidence of ancient petroglyphs, rock and cave paintings, and other assorted cultural treasures. The pictures will not only prove the existence of an extra-terrestrial presence at Earth for the past 10,000+ years but will also show you detailed renderings of the types of craft that are being employed that were recorded in exacting detail by skilled artists of numerous cultures over thousands of years. This amazingly includes the inner contents of several of these craft. While you may have seen many of these pictures before you now will get to see them in an entirely new light.
Best wishes all! ~ Edward
Introduction to The WANA Hypothesis
STARSHIP DESIGN 101
If I was thinking of designing an interstellar spacecraft capable of traveling between the stars for the purpose of exploration or conquest it would bear most of the same characteristics of the ancient craft that we find recorded in and on stone.
Since space is not empty and hydrogen and helium ions have mass, it might be smart to shape the craft like the nose cone of a rocket or missile because to travel long distances through space you want to get wherever you are heading as fast as possible. A cone not only provides the least resistance to interstellar winds but is also an extremely strong form in itself which is why things from egg shells to amphora don't break as easily as one would expect.
The next issue of consideration would be size. The bigger the better is what I say since resources and energy are unlimited. If the goal is to check out every nook and cranny in the galaxy you might even want to create a giant fleet of accessory space craft to be housed in the largest of the motherships for those inconvenient off-the-beaten-path stellar excursions. The accessory spacecraft would also have it's own fleet of even smaller spacecraft and ion it would go until the last craft was equipped with merely a large fleet of specialized probes.
This is what I believe we are witnessing in the largest of craft... a giant hollow cone that radiates light downwards to resemble the familiar unmoving overhead "saturn" / "superior sun" / "circle within circle star" when directly overhead or pointing in the direction of the observer, and when view at great distance from the side it looks like a giant cone or "celestial mountain" as it may also be called. When the sun catches the craft from below it reflects from the inside or the internal light creates a ring around the edge that resembles the "crescent" shape or "bull's horns".
For a sequence depicting the movement it would look like a 1st century BC cemetery stele in Tophet Carthage

2 views, overhead and side, can be seen on the "Victory Stele of Naram Sin" which I noticed actually has 3 overhead "saturns" rather than 2. In this case the "cosmic mountain" is just the 4th spacecraft.

At the Petroglifos do Castrinho de Conxo in Spain we see a medium size craft and some smaller craft that look like one immediately below at the Three Rivers petroglyphs.


They can also be found at Petroglyphs in Ontario where we see the 'circle in circle star' squatterman figure plus a cone squatterman figure along with several representations of the cones with a 'cap'. The squattermen suggest an electrical discharge to ground.


The next components to examine are the South-Western US and Mexican representations of the ET presence. They are among the smallest and best drawn entities around. All of the answers you are looking for are there.
