i knew someone would bring up the moon conspiracy! to be honest, i rather enjoy talking about it
i believe we landed on the moon, without a doubt. But we have to question these types of things.
A lot of the conspiracy ideas may sound good, but upon investigation they lose it.
Just one example, like you said, the flag waving. People came up with that one because the whole flag is clearly visible, when we all know a flag droops down. NASA thought that out, there was a bar at the top of the flag, because what would be the point of it if the flag couldn't even be seen? (little side fact, the flag from Apollo 11, the first one placed up there is actually knocked over. they spent billions training and sending them up there, but not once told them to place the flag a little ways away from the lunar lander (LM) so that when they took off, it wouldn't knock over the flag)
Ha, and i saw someone comment about Al Shepards golf ball. Supposedly since he couldn't get a good swing in the suit, it really only landed a few feet away, but off the sight of the TV camera, so he claimed it went "for miles and miles"
