Space X's Starship rockets are far more powerful, advanced and capable than the Apollo ones. Space Technology has not gone backwards, although it did stand still for 40 years.
The more plausible explanation for the success of the Moon landings after only a short period of NASA's existence and the later failures, waste and mediocrity is politics and government corruption.
There is also unfakeable physical evidence of the Moon Landings in the form of the Moon rocks.
Just because the US government has gone so bad now doesn't mean it faked events over 50 years ago.
Thank you for your comment, there is a lot to unpack here. IF you have time, look deeper into these pieces of evidence, with an open mind and without prejudice. Nobody wakes up one morning and decides to contradict an opinion that has been accepted by the vast majority of people. I believe most people are truth-loving people. The moon landing and the nature of the earth are very uncomfortable subjects, because it puts into question the very foundation of our technological pride and our accomplishments as a collective species. Anyone interested in serious dive into proving the moon landings as authentic (with intellectual honesty) are about to embark on a very fascinating history lesson.
