You don't have to trust anyone.
There are at the moment 6 retroreflectors on the moon (3 left by NASA, 2 by Russia, and a recent one from India).
The one from Apollo 11 is the LRRR (Laser Ranging Retroreflector) and is located at Mare Tranquillitatis.
You can read here more about how they send lasers and measure the time it takes for the laser to bounce back from those retroreflectors.
So the astronauts had to put those mirrors down on the surface or could it be mounted on top of a rover?

Some have been put there by astronauts, others by robots
