Our sun is one of a 100 billion stars in our galaxy. Our galaxy is one of billions of galaxies populating the universe. It would be the height of presumption to think that we are the only living thing in that enormous immensity -– Wernher Von Braun
To suppose that earth is the only populated world in infinite space is as absurd as to believe that in an entire field sown with millet, only one grain will grow — Metrodorus of Chios 4th century B.C.

Introduction

Robert Graves (Graves 1968) writes, “Mythology is the study of whatever religious or heroic legends are so foreign to a student’s experience that he cannot believe them to be true; hence the English adjective ‘mythical’ meaning ‘incredible’; hence the omission from standard European mythologies of all Biblical narrative even when closely paralleled by myths from Persia, Babylonia, Egypt and Greece.”
For many modern skeptics the world’s oldest writings, on clay, stone and papyrus, is simply myth. However, if we dismiss all of the ancient literature and inscriptions – the Bible, the Koran, the Mahabharata, and the thousands of clay tablets from Mesopotamia – as too incredible to believe, we would still have to deal with the question of the physical evidence. Who built the ancient megalithic structures? How were they built? Why the practice of building pyramids at ancient sites all over Earth for a period or time, and then suddenly abandon them? Who marked the Earth’s surface with gigantic lines and figures? Who created the astonishing artwork on Mars? Why and how were these things done? In this space age, with it’s remarkable technological advances, it is becoming apparent that the “miracles”, and other seemingly supernatural events reported in ancient texts, the megalithic constructions, and the enigmatic lines and artwork over the Earth, resulted from an advanced technology which was incomprehensible and indescribable by the ancient human observers. On these pages we take the position that there is a reasonable explanation, within natural law, for these mysteries.
In this series of articles we will review the evidence that these mysteries are attributable to ancient astronauts; extraterrestrials who have visited Earth in prehistoric and historical times, and have interacted with humans or their evolutionary predecessors, i.e. what authors throughout history have referred to as “the gods”.
And it came to pass on the third day in the morning, there were thunders and lightnings, and a thick cloud upon the mount, and the voice of the trumpets exceeding loud; so that all the people that was in the camp trembled…And mount Sinai was altogether on a smoke, because the Lord descended upon it in fire; and the smoke thereof ascended as the smoke of a furnace, and the whole mount quaked greatly…And the voice of the trumpet sounded long, and waxed louder and louder… –- Exodus 19:16-19.

The AA Hypothesis inBrief

AAs first came to Earth many millennia ago. They were beings whose biology was similar to modern humans. They created modern mankind by mixing their genetic makeup with that of sub-humans. The purpose of mankind was to serve the AAs, principally by providing food and mining and construction labor. The AAs did not allow humans to view them – only their symbols (idols), suggesting that their appearance was frightening; however humans were occasionally permitted to see their emissaries, e.g. “geniuses” and “angels”. They also would not allow humans near them, except priests who had cleansed and covered themselves and spread a germicide, suggesting their susceptibility to earthly diseases. They apparently moved about the Earth in spacecraft using chemical fuel, and only landed on mountaintops or other rocky outcroppings; this reduced the dust and provided physical protection from humans, and disease control. The earliest sites had a cave under the rock that protected the priests during the coming and going of the spacecraft. Later they built, or provided humans with tools to build, cyclopean structures – huge earthen, baked brick, or stone ceremonial platforms and pyramids, which served as landmarks and as landing and feeding sites. Since they had little defense against earthly bacteria, they developed methods to nourish themselves with the vapors emanating from food and drink which humans provided and burned for them. The food and drink was provided through the custom of sacrifice, the burning of the meat and blood of animals, and sometimes humans, which the AAs demanded. These ceremonial and feeding sites were located all over the world, most on or near the current equator or near earlier pole-shifted equators. They taught humans agriculture, astronomy, engineering, and provided the first laws. They then departed from the face of Mankind.
