Welcome to the board, Ken.

There are many lines of evidence that the mainstream will use to explain why we accept that the moon landings happened, but I'll just go with one for now, and ask you to defend your theory against this one;

We have a large quantity of moon rocks that were supposedly brought back by the returning Apollo astronauts. These have been widely distributed and studied, and appear to have come from the moon. They cannot have come naturally from earth (no weathering at all on them), and no-one has suggested how they could have been made.

So, how, if we did not go to the moon, do we have all of these moon rocks?
