I don’t believe the pyramids are only 5000 years old either
There is way to much weathering on the sphinx to be that young. And there was much water in the area. That was not there 5000 years ago.
I just recently observed a strange set of lines in africa that look lick ancient civilizations that are long gone
Hear about “The Old Man” in Chesterton’s Everlasting Man. https://www.youtube.com/watch?v=K3uO_8LtV64
What do the experts think the lines represent?
Parallel ridges, about 25-40 feet high, separating the “tracks”, which have greenery in the bottoms; 1-1.5 miles, mostly 1.2, from crest to crest. Mainly Vee shaped, rather than flat bottomed.
I used Google Earth Pro, which has continuous surface altitude readout as I scroll; and the ruler function enabled. Seems more natural topo than man made. YMMV
I looked at the image and thought it might be alternating tin beds of hard rock and soft rock (say sandstone and siltstone) that are tipped near vertical and then weather out to cause linear depressions.
The above link says that they are sand dune features - so the dry (and light-colored) hills, and the wetter, greener (darker) troughs. Still though - very cool looking.
