There is literally a mirror in the moon you can get a reflection from it you know where to look. Mom landing hoaxers don't need evidence to believe what they believe.
I mean, it's a little more difficult than that. You need an expensive high powered laser only available at universities and precision calibration and timing equipment to fire and detect the return pulse.
It's not like you can just pull out a hobby telescope and be like "oh look, a tiny mirror next to an american flag"
