<QUOTE>My friend told me some story that apparently there were skeletons found on the moon. I tried doing some research</QUOTE>

I'm sorry, and don't take it the wrong way, but you were dumb in doing that. It's not you who's supposed to do the research. You should have asked him on which part of the Moon they were (I wouldn't be surprised if your friend would have told you something as ridiculous as citing the title of a Pink Floyd album).

You have to learn to ask the right questions to save yourself of trouble.

- "In what part of the Moon are those skeletons?"

- "When did they got there?"

- "Who put them there?"

- "How many?"

- "Why?" (the most important one)

- "How did you find that out?"

When you start asking questions such as those, more often than not you see that the people who are trying to pass you those stories start getting visibly uncomfortable; often this discomfort comes from their realization that they didn't thought of those questions and they're realizing it for the first time.

See what I mean?

<QUOTE>Maybe someone has done some research already, are there any credible sources at all?</QUOTE>

I'd like to know too.

Because there are satellites orbiting the Moon low enough to take pictures, as in RIGHT NOW.

http://www.nasa.gov/mission_pages/apollo/revisited... and http://grail.nasa.gov/

So finding skeletons along with the space suits, and the remains of a crashed spacescraft that would have been necessary to send it, would have to show up in pictures.

Perhaps your friend meant "skeletons of spacecraft"? http://en.wikipedia.org/wiki/Luna_8

But as far as we know, these had no one inside them. There's no way to know whether there were people inside them or not. So if your friend tries to use Luna 8 as an instance to confirm his story, remind him that it could be a plastic skeleton, a teddy bear, or Rush Limbaugh inside the Luna 8 -- because "you can't prove that it isn't there".
