We have accomplished exploration that is magnitudes more complex than putting man on the moon. Putting a man on the moon was more of a publicity stunt done to stay ahead of the USSR technologically. We not only did it once, we did it 7 times. We also have numerous unmanned landings. Once we accomplished it, there was really no point to keeping the Apollo program going.
Now we have put numerous probes on planets around our solar system much rather than the moon, we have flown 13 successful missions to Mars (4 other countries have flown only one each), including multiple rovers on the Martian surface.
We have flown missions to land probes on moving asteroids, collected samples, and returned them to earth.
People who think the Apollo missions were the pinnacle of space exploration obviously have not been following all the cool shot we have been doing for the past 55 years. We have gone way beyond the Apollo missions technologically, and we are only getting started.
I guess it’s easier to just refuse to believe we ever did it though. LOL. People truly are incredulous and stupid. “I can’t comprehend it so it must not be true” is their mantra. Keep disbelieving while the world passes you by.
