I thought satellites were fake Tom
Satellites exist. They're just not in orbit.
On the subject of data, this person has successfully echoed signals off the moon. His website contains an account of the first echo he achieved on April 26, 2005. He states that "Echoes return approximately 2.5 seconds".
What is wrong with this "proof" then?
Your proof is unacceptable for a number of reasons. Firstly even bouncing a signal off of a dimly reflective celestial body is impossible due atmosphere and signal degradation and siffusion issues. Secondly, even if it were possible, how do you know that the signal isn't passing up the 32 mile diameter moon and bouncing off the surface of the Celestial Dome behind it?
Well you can test to see if signals bounce off of some sort of Celestial Dome fairly easy, just send out two radio signals, one at the moon and one pointing slightly away from the moon. If they are bouncing off the Dome, than both would come back.
Also, the moon would reflect radio waves. Radio waves will bounce off of all sorts of stuff, even if it isn't highly reflective to normal light.
