Don't you agree it is done in FAITH (nasa told us so! ughh)
what else is it?
But it's not just NASA. It's the space programs of other countries. It's independent observers that tracked the missions. It's the thousands of scientists since then who have never shown any reason why the landings *couldn't* have occurred, and supported the principles on which they did.
It comes down to, is it reasonable to have faith that the combined observations of hundreds of thousands (perhaps millions) of people are correct? Or to assume that some evil entity has lied to us, to the point of warping even our understanding of the physical laws of the universe, in order to persuade us that the landings occurred.
You, like many hoax supporters, take refuge in solipsism. How, you ask, can we be sure we are seeing the True Truth? Perhaps we're living in our own version of the Truman Show, perpetually lied to and tricked. How would we know otherwise? Perhaps. But what would a rational person think is the most likely interpretation? You may proclaim "It could all just be a Grand Illusion," but I'm not planning to base my interpretation of reality on that.
