That is complete nonsense. You can't even see the lunar landers from 
Earth. The resolution limits for ground based observations of the moon 
with the largest instruments are worse than for any other solar system 
object since they cannot track it well. The Moon is in orbit around the 
Earth and as such is a nuisance to track.

Most ground based optical scopes are limited to about 0.25" resolution 
on the most exceptional nights with 0.5" being more typical ~ 2x10^-6 
rad. At the lunar surface under the most favourable supermoon conditions 
when the moon is <360000km away this translates to being able to resolve 
features that are about 720m across. You can see high contrast features 
that are smaller but they will be blurred by the PSF. Even with state of 
the art image processing against a white background the resolution limit 
would be around 200m absolute tops.

But don't take my word for it here is the RIT.edu site

RIT didn't seem to be playing today so here is the wayback version

There is incidentally a really good supermoon this month on 14th Nov - 
about as big as it ever gets (with a tidal range to match).

They are morons without a shadow of a doubt, but there is no Earth based 
scope that can resolve footprints on the moon - not even close. Even the 
LEM itself is an order of magnitude beyond what is possible with the 
best Earth based AO systems (if they could track the moon). Hardly any 
of the main scientific optical telescopes can even track the moon to 
begin with - it would not be worthwhile.

The best that has ever been acheived from the ground is ESO's 8.2m YEPUN 
scope which managed 0.07" arc aka 130m. They tricked it into guiding on 
a nearby mountain as part of an AO engineering test.

I don't understand how this cult of "we didn't go to the moon" grew up. 
Even the *Russians* accept that the US landed a man on the moon!

Both sides intercepted each others interplanetary telemetry.
