Wondjina rock art
The Wondjina rock art in Australia is the best example of ancient aliens in art on the continent. To be fair, there are certainly some big-eyed, oddly shaped humanoids in these works of art. These were important paintings to Aboriginals, who freshened the paint so often that some areas have dozens of layers of paint. The question is whether these paintings depict aliens. Well, if you think the Aboriginal weather spirits were aliens, then yes.

Sego Canyon drawings
The Sego Canyon petroglyphs are interesting in that they have art from at least three native cultures spanning nearly 8,000 years. Some of these pieces are clearly of buffalo, horses and white men. Others are a bit more bug-eyed and oddly shaped. These are what many believe are drawings of ancient aliens.

Where the Annunaki reptilian aliens?
We know that Egypt is a hotbed for ancient alien speculation. Did Aliens give them the technology for the pyramids? Did they build the Sphinx? The ancient civilizations of the Middle East give us equal questions. The Annunaki were gods mentioned in several ancient texts, including the Epic of Gilgamesh. They are also portrayed in ancient art. Some believe these beings were actually aliens who visited the people who invented writing, perhaps triggering the technological growth of humans.
