I know another one story about ETs. In the last mission once the landed module departured from the moon, landed an Ufo and a lot of aliens started to examinate what was left by man, the funny thing is the speech between the orbiting module and the landing module received by an radio-amauteur, the man in the orbiting module didn't care about the ETs, his worry was if they were touching the mirrors left on the moon, he asked several times about the mirrors!

Stupidity also evolves!
