We definitely landed on the moon.
It would be impossible to fake the conditions found on the moon. For example, the rocks that they brought back contained chemical signatures found nowhere on the Earth and this could not be faked.
The astronauts placed reflectors on the surface of the moon that we still routinely bounce laser beams off of in order to measure the moon's distance from the Earth.
Also, it would have cost much much more to fake the broadcasts, evidence, scientific instruments, etc. than it cost to actually go to the moon.
There are numerous websites debunking this myth. For example:
There is a principal in science called Occam's Razor. It states that all things being equal, the simplest explanation is usually correct.
Does it make more sense that we landed on the moon, or that there has been a massive coverup within NASA and the entire scientific community for 30+ years with absolutely no one coming forward to reveal that they were faked?
Does it make more sense that all of the photographs, films, rock samples, etc. are authentic, or that they were somehow faked at enormous technological cost so expertly that scientists have been fooled all this time?
I think you know the answer.
