If we can land a man on the moon, why can't we prove it?

One of my favorite websites about the manned moon landing hoax is titled "if we can land a man on the moon, why can't we land a man on the moon?". That's pretty funny-- and pithy. I'd like to ask it in this way-- "If we can land a man on the moon, why can't we prove it?". Here's a picture of the lunar lander, presumably on the moon. [+]. Look at the crappy sheet metal joins. This thing presumably was on the moon with two men in it? Okay-- here's the thing. I have to suspended MORE of my disbelief to accomodate the idea that we DID land on the moon than with the idea that we did NOT land on the moon. This lander makes it very difficult to suspend my DISbelief that it contained two men who landed on the moon.
