More like 30 years.But we know where they were. If we find something that exists where there have been no landings, then that would be a piece of evidence.
What were people, who hadn't even invented writing yet 10,000 years ago, doing on the Moon?
I don't know if there were humans on the moon before 10,000 years ago or not. The fact that there is no writings before 10,000 years ago means no one knows. Probably wasn't but weather patterns, volcanos, plate tectonics, and comet/asteroid strikes destroy evidence so quickly on earth that there could've been an entire civilization and it could have sunk to the bottom of the ocean or under 200 ft. of soil. Here's an ancient Egyptian carving at Abydos.
Looks like a tank, helicopter, glider, and a blimp. All in the same carving. If these were scattered, it wouldn't be so interesting, but when all four are in the same carving, you have to wonder what was the carver going off of.
One of the more interesting things about Abydos is the subterrenean passageways filled with water, the 'water hallways'. Also, the structure of the largest building is megalithic with several ton plate stones atop massive columns, all perfectly carved ten-thousand or more years ago. Is there a link between Abydos and the submerged structures off the coast of Okinawa? We'll see! [For pictures of the Okinawan structures, visit Graham Handcock's website and click on the photos made by his talented photographer wife. As best anyone can tell so far, the structures were last above sea level during the last ice age, which came to a slow, grinding end ~10,000 years ago when the fertile plains of Giza began to dry up and the Sphinx was already several thousand years old, as evidenced by errosion markings on the base stones of the compound.]

If these were scattered, it wouldn't be so interesting, but when all four are in the same carving, you have to wonder what was the carver going off of. Actually it looks like a helicopter flying over a dome and something striking the dome, a tank, a blimp and a drone.
