Out of place artifacts
I've always been fascinated by these artifacts; especially ones that predate humanity or are of unknown origin.
I think some of these could be indications that we've been visited by extraterrestrials in the distant past; the Baigong Pipes being a good example of such.
Another interesting one is the stone spheres of Costa Rica. Has anyone ever done any research into these kinds of things?
Here's Wikipedia's list of out of place artifacts:
