There are mysterious Nazca-like lines in Central Asia. Very few know about them in the West. But there will be articles about it; I am also working on an article about ancient petroglyphs in Central Asia that depict dinosaur-like creature (and other gigantic creatures that clearly were out of place and time there..). And a few other surprises from Eurasia...including tremendously important rock carvings that depict "UFOs", and strange humanoids (Central Asia, and elsewhere).
Another area of keen interest to all researchers should be China, and
its remarkable history of UFO visitations. My area of research is
Sichuan Province. But there is so much more there, from ancient
sightings to modern cases.
