Did man really walk on the moon or was it a hoax?

i just watched a doentary with really strong points and arguments about the supposed lunar landings. it seems so damn true i don't know what to believe. anyway i don't think anybody is capable of fooling millions of people all around the world and get away with it. so if it is in fact true that man did walk on the moon, six times planting the american flag every time, then it shouldn't be hard for us to use a very powerful telescope that can focus the lunar surface and find this flags and maybe their footprints right. so has this been done already or there is just no telescope that powerful? and is there anybody else out there that also thinks it's true man walked on the moon and what is your supporting evidence. thenx a bunch to all that will not insult me as you reply.
