I was just reading a thread about this... I think on Space.com? Anyway, the hoax theories have been completely debunked. Among the notable hoax "evidence"...
- The flag appears to be waving.
The flag is not waving. There is not wind on the moon. That's why the dust in the videos flies up and then straight back down. There's a little horizontal bar on the flags they use in zero-G. When the astronauts went to extend the flag along the bar they didn't pull it out all the way so it ended up hanging with little folds in it, making it look a little bit like it was waving. Now astronauts always deploy the flag only partially so it looks like it's waving.
2. Identical Hills
Two sets of two pictures taken from completely different locations show the same hills in the bg. However NASA later made a press release correcting that info. The pictures were taken from only a few meters apart in one case, and in the other they were taken from much farther away but looking in the same direction. Because the moon has no atmostphere objects don't decrease in clarity depending on distance, thus the hills look nearly the same.
3. No objects left on the moon
Even with our strongest telescopes it would be impossible to pick out debris on the moon.
In fact... here's a good debunking site.
