Apparently they say they did it with a super computer in 1969 that had less processing power than a watch today. Those old computers that used spools of tape.
And now in 2024 we don't have the technology to get "back" to the moon. Work that one out.
Well the "super computer" argument is just not good because this wasnt an all purpose computer. This was specially build for this task. There are tons of special purpose chips today that wont be able to do general purpuse computing but crush a beefy pc in special tasks. Video encoding for example or tons of other tasks.
If you are actually arguing that our accomplishments in space aren't real, in good faith, you are very uneducated on the topic.
If the US made up the moon landing, we have many nations that have the technology to call out the lie. Yet none have, not even supposed 'enemies' of the US.
That one seems harder to 'work out', than your assumption that we couldn't go to space with the technology at the time.
