I believe Earth is NOT flat. I don't believe there are aliens in Area 51.
But this question is factually not very convincing and it is, did we actually land on moon in 1969.
There are many compelling evidences, facts etc that proves that indeed we landed on moon.
But even in 21st century where there an accident with Kalpana Chawla who merely went to space and came back, it sounds too good to be true that in 1969, we landed on the moon which is around 300000 kms or 186000 miles from the Earth with those time of technologies and successfully came back. Remember, the first apple computer was launched in 1976.
I'm not saying we didn't, I'm just saying that it's not really a question that can be debunked like other theories which says Earth is flat.
I think it will be true if the flight was documented in detailed. I get your point about computer, probably you are thinking how to they lauch a rocket in space going to the moon if our computers are not so advance. I don't think there was another way to do it without using computers. That is why I believe that they just shoot it in a location here in Earth that is like the surface of moon. After years, maybe they can able to go to the moon and just gather information and added documentation about their flight and to the moon itself.
It was not much about the computer. Computer is still not a huge thing for spaceflights.
It's metallurgy and Physics mostly, it's about speed and angles. I was too first suspicious how they were able to land on moon back then but has not rocket to reach moon now.
US was able to put men on moon back then because they had no funding restrictions and safety were not a topic. Even today they can repeat it but they don't have the funds for the stunt.
