Until today, I had never once heard anyone ever mention these "reflectors" which apparently were placed on the Moon at the landing site in order to verify from Earth that humans were there.
Many conspiracists hold that the Apollo Moon landings were a hoax; however, empirical evidence is readily available to show that human Moon landings did occur. Anyone on Earth with an appropriate laser and telescope system can bounce laser beams off three retroreflector arrays left on the Moon by Apollo 11, 14 and 15, verifying deployment of the Lunar Laser Ranging Experiment at historically documented Apollo Moon landing sites and so proving equipment constructed on Earth was successfully transported to the surface of the Moon.
It further links to: https://en.wikipedia.org/wiki/Lunar_Laser_Ranging_experiment
However, the second link doesn't mention anything about the purpose of this being to verify that humans landed on the Moon. It goes on to mention the year "1962", which is before any humans had allegedly set foot on the Moon, and apparently they could still do the "experiment" without any reflectors in place, so what does this really prove?
This could become a conspiracy theory in itself; that they added this story about the reflectors long after the fact. However, I'm not saying anything -- I'm just wondering what the point of them was and why this has never been brought up as a way to verify the moon landings, if almost anyone can do it with some equipment.
