The first time humanity was able to land on the lunar surface was on July 20, 1969, when Neil Armstrong and Buzz Aldrin trod carefully on the celestial body. After this momentous occasion, the last time someone landed on the moon was in 1972, which was Gene Cernan and Harrison Schmitt for the Apollo 17 mission. Have you ever wondered why there aren’t more recent crewed moon landings? WatchMojo explains the real reason why we haven’t attempted to return to the moon. Check the full video here!

Sure, we don't have access to the same materials. (We're not going to use asbestos now.) And we don't have people with the same skills.
But we also have better materials and alternative skills. 10 years ago, Pratt & Whitney Aerodyne designed the F-1B (see https://en.wikipedia.org/wiki/Rocketdyne_F-1#F-1B_booster ) based on the F-1 engine, but using a better design and more advanced construction techniques. The design estimate was an engine 15% more powerful than the most advanced Apollo-era engine, cheaper to build, and more reliable.

The reason why we don't send people to the moon is there's no good reason which justifies the cost, both in human lives and financial.
