To put it bluntly, there are laser reflectors on the moon's surface put there by humans. We know they were put there by humans and not done with a remote vehicle because from a technological standpoint it was a lot harder, if not impossible to so at that time.
The so-called evidence of no moon landing far outweighing the evidence that it actually happened is laughable.
I love your logic that you can't leave clear footprints in dirt/dust that is at 0% moisture content. How so?
It's also quite possible for larger rocks to be relatively dust-free on the moon as there is no wind to move the dust around.
Which brings up the next bit of "evidence" that the moon landing was faked; the flag. We see the flag unfurled and straight out away from its pole. Now, how can a flag appear to be flapping in the breeze when there's no atmosphere on the moon? Simple. You take a rod or dowel, run it along the length of the top of the flag and secure it. And of course the flag isn't going to droop with only 1/7 the gravity there is on Earth acting on something that weighs very little.
My other favourite argument is shadows in photos going the wrong way. Again, easy explanation. Artificial lighting was used to take the pictures.
Then there are the most recent photos from the Lunar Reconnaissance Orbiter clearly showing the markings of human activity on the moon.
In fact, there has never been a compelling argument proving that the moon landings were faked.
