The lunar landers measured 14 feet by 13.3 feet square.
In order to see the lander, a telescope 1000 times more powerful than mine might possibly show a bright pixel, MAYBE. Couple that with atmospheric distortion that tends to blur everything, using even the most powerful earth based telescope it would be completely impossible to even come close to seeing any detail of any of the landing sites.
To take it one step farther - what about Hubble? Can it see one of the landing sites? Well, to quote "Hubblesite.org"...
"Can Hubble see the Apollo landing sites on the Moon?
No, Hubble cannot take photos of the Apollo landing sites.
An object on the Moon 4 meters (4.37 yards) across, viewed from HST, would be about 0.002 arcsec in size. The highest resolution instrument currently on HST is the Advanced Camera for Surveys at 0.03 arcsec. So anything we left on the Moon cannot be resolved in any HST image. It would just appear as a dot."
Remember, the moon is about 250,000 miles away, and in order to see something 14 feet square at that distance would take one large telescope in orbit. The best we can do is photograph the terrain near the landing sites, but we cannot see the site itself.
