As far as those who believe those conspiracy theories, you can visit any astronomical observatory on the planet that has laser reflector telescope. During Apollo missions a large laser reflector was places on the moon near to where the craft was landed to measure accurate distance of moon from the earth. That is still there and countless observatories have verified that its really up there since 1970s.
As far as computation power goes, why do u people underestimate simple mathematics and physics. These guys did not depend on the crafty supercomputers but all numbers were crunched manually and just fed into navigation analog computer.
And honestly a college graduate will be able to do that if given enough data. You dont need supercomputers to go to moon. That is the reason why these missions were also very dangerous. As if something went wrong they have to diagnose and correct it manually. Thats the reason incidents like Apollo 13 happened.
at last some sense on this thread
