Similar to the way archaeologists uncover lost civilizations on Earth by analyzing the artifacts left behind, various researchers believe the past presence of advanced aliens could be detected in a similar manner. This is a reasonable approach. It has historically provided evidence of civilizations that appear to have simply vanished. For example, the Mayan calendar is supposedly predicting the end of the world on December 21, 2012. Unfortunately, this is a poor example of a lost civilization, since it never disappeared. In fact, the Maya and their decedents still populate the Maya area, and continue to honor traditions that date back centuries. Millions of Mayans still speak the Mayan language. As for the Maya calendar, most scholars do not interpret it to predict the end of the world.

A real example of a lost civilization can be found in our own North American backyard. The Anasazi lived in the bordering parts of Utah, Arizona, New Mexico, and Colorado. The Anasazi civilization emerged about 1100 BC, and appeared to vanish about 1100 AD. However, did they really vanish? Most archeologist think not. They did abandon their traditional homeland. In a number of cases, the “lost” civilizations are not lost. They move to a different location for reasons that generally relate to survival, like water and food availability. However, the point is that we know about the Anasazi civilization by studying the artifacts lefts behind, including their dwellings, pottery, tools, and the like.

Proponents of ancient alien visits to Earth point to the numerous alien-like artifacts. These include:

  • References in religious texts, such as the Book of Ezekiel (Biblical Old Testament)
  • Physical evidence such as Nazca Lines, which depict drawings that can only be fully seen from the air (Peru)
  • Ancient aircraft-type models, like the Saqqara Bird (1898 excavation of the Pa-di-Imen tomb in Saqqara, Egypt), and small gold model “planes” (Central America and coastal areas of South America)
  • Unusual ancient monuments and ruins such as the Giza pyramids in Egypt, Machu Picchu in Peru, Baalbek in Lebanon, the Moai on Easter Island, and Stonehenge in England. Proponents of ancient alien visits argue these structures could not have been built without alien help. They argue that the ability to build them was beyond the capability of humankind at the time they were built.

This is a sampling that proponents of ancient aliens provide as evidence that the Earth has been visited since ancient times by advanced aliens. Numerous books forward this theory. The most famous was written by Erich von Däniken, and published in 1968 (Chariots of the Gods?).

Obviously, this is a speculative theory, and not everyone agrees. In fact, there is considerable disagreement. Several disagree on religious grounds, like the Christian creationist community. Other critics simply say the evidence is subject to various interpretations. In reality, we have not found irrefutable evidence—the “smoking gun.” For example, if we found an electromagnetic transmitter (a radio) of unknown origin inside a newly discovered 3,000-year-old pyramid, that would be a smoking gun.
