I don't know whether we went to the moon or not. I wish I could know for sure.
Physical samples, miles of film, and recent imagery of the landing sites are not sufficient? What further evidence would you require?
Normally these videos trying to debunk the moon landing bore me, but this one is more interesting than others I've seen. Why haven't we gone back? Or have we?
“We” as in America have sent unmanned missions back to the Moon since Apollo (Clementine, Lunar Prospector, Lunar Reconnaissance Orbiter, GRAIL). LRO has imaged the Apollo landing sites.
China’s sent several surface probes and rovers, including one on the far side.
We haven’t sent people back because nobody’s managed to convince Congress to pay for it. That
may change with the Artemis program, but frankly I don’t expect it to survive the election in November.
SpaceX has plans for a private mission called Dear Moon, which will send people around the Moon but not land on the surface. Not sure what the timeline is on that.
