Just watched a show, seemed pretty questionable, that stated that there is a cave in the Grand Canyon with ancient Egyptian relics, because they had traveled there. Apparently, some guy made a boat out of papaya to test to see if it was possible, and I guess it was.
Is there any indication this actually happened?
There have been no ancient Egyptian artifacts found in situ anywhere in the New World. Thor Heyerdahls expedition from South America across the Pacific in 1947 merely showed that long distance sea travel in the distant past was possible, not that it actually occurred.
