If we have such powerful telescopes on Earth - why can't we use them to find evidence of the moon landing?

Have you not thought it through?

The best available telescopes have a resolution of about 300 meters per pixel on the moons surface, not very good for picking out footprints !

We CAN 'see' the reflector that was put there, though. If you shine a laser at the area, it reflects so it must be there.

There must be some sort of Earth comparison you could work out.  They will have a specific area of the Moon to concentrate so that narrows it down.   It maybe something like trying to spot a beachball in the cluttered land area of Norfolk  from 10,000 feet (with a lot of haze on the day), whatever. 

The only 'amateur' evidence I know of is a bloke picking up voices (not very clear) on the radio link on the famous day in 1969..deffo comming from the Moon because his aerial was pointing at the Moon.

If they had been in low earth orbit, they would have not been audible for long so that (as well as everything else) seems to clinch it.

It was Jan Ottens (PA0SSB) in Holland who had a large dish for bouncing signals off the Moon who claims to have heard the Apollo comand module.  There may have been others. 

""He also used the dish to
listen to the command module S-band transmissions, but he could only
hear the subcarrier which they used, not enough gain / low NF to
demodulate, but from the modulation you could clearly tell that an
astronaut was talking. And, you could clearly distinguish the Doppler
shift and hear the carrier drop out suddenly when it would go on the
"flipside" of the moon.""

 There was an episode of mythbusters the other night. They went to the observatory where they actually shoot the laser that reflects off the mirror placed by the Apollo astronauts. It was on the discovery channel or the history channel which you can find on the web; check it out for yourself. TECHFACTOR:OUT

When the Jodrel bank radio telescope was first put into operation a demonstration was broadcast of speech bounced of the moon using a small taxicab vhf communications set (its wonderful what you can do if you have access to a large dish).

My pal used to bounce signals off the Moon.

I would be interested to know what is the possibility of modulating the laser beam that is reflected from the corner reflectors placed on the moon.
Would the bandwith provide a useful communications channel.

Clouds might reduce the usability under many circs.
