So tell me again, what is the reason that we can't photograph the U.S.flag on the moon?
What would be the point?
To prove it is actually there, some people believe that the moon landings were faked.
Well,
A.) Those people are dumb, and should not be pandered to; and
B.) If they went to all the trouble of faking a multibillion dollar project using 1960s technology, why wouldn't they be able to generate a couple of fake photographs using 21st century photo editing software? In other words, any such pics would be dismissed as fakes by the aforementioned dumb people.
