I wonder that about some of the technology we use in everyday life.
I am not a STEM person, so I can’t even begin to get my head around how complex and difficult it is to pull off a lunar landing. It is kind of like Mark Twain’s comment about a dog that can walk on its back legs: the marvel is not that it’s done well, but that it’s done at all.
I remember reading a rumor that the Soviets attempted a lunar landing before we made it, and the spacecraft flew past the moon.
Never happened - they used sledge hammers on their “shuttle”
