UFOs depicted In petroglyphs
Throughout the world, petroglyphs that seem to depict alien contact can be found.
Last week I ran across a mention of UFOs and aliens as depicted in petroglyphs, and I have been utterly smitten with the topic ever since. Petroglyphs abound throughout the world, with many found right here in the United States. Petroglyphs themselves are fascinating, being a record of someone's doodle (or religious ceremony, or depiction of real life events, or whatever other meaning you want to assign to them - most likely, "all of the above, depending on the petroglyph") from tens of thousands of years ago.
Petroglyphs are art that was carved or chiseled directly into rock in prehistoric times. Unlike other forms of prehistoric art (like cave paintings), petroglyphs would have been both extremely difficult to create and permanent. Think about how hard it would be to carve a drawing into a rock face: obviously you would only do it if you had a real, burning need to do so. Petroglyphs are the ultimate form of permanent art, communicating across the space of thousands of years.
