The problem with this is it's a huge logical fallacy (specifically, the argument from personal incredulity). However, just because you can't imagine or understand something doesn't mean it's not true. It truly was an amazing, Herculean effort. But just because the technology was less advanced doesn't mean it wasn't sufficient to pull it off. The construction of the pyramids (not to mention lining them up so that their faces face the four cardinal directions) would be a huge technological achievement today. The construction of Stonehenge included the transport and erection of stones that weighed 20-25 tons and was completed by roughly 2000 BC. These are incredible accomplishments, and we still don't know how they pulled off parts of it (as far as I know). But there they are (and no, the aliens didn't help them).
There's no problem viewing something as awe-inspiring as the moon loading with a healthy dose of skepticism, but after a careful review of the evidence, the conclusion is pretty clear. There's the existence of retroreflectors (the mirrors mentioned in an earlier post), the moon rocks and dust collected, the independent observations of other countries and agencies (the Russians specifically, who would have had the greatest motivation to prove the reality of a hoax), and the subsequent photos and videos of the landing site by NASA and other space agencies. In addition, there's the complete and thorough debunking of all of the theories espoused by the hoax proponents. It's all there as public record and easy to access.
I only read your first line. You asked me why I don't believe it, and I told you why I don't. Plain and simple. I am not trying to convince anyone to change their minds and I am not going to engage because you want to spout fallacies.
I also saw that most of what you wrote is a copy and paste exercise from Wikipedia....
