Its verifiable because the rest of the world has radar, too, and tracked our rockets going to the moon.
And we had a dozen astronauts walk on the moon and come back with evidence, like moon rocks.
And thousands of engineers at NASA watched the whole thing happen as witnesses.
And we have the Apollo 12 crew that landed at the Surveyor 3 moon probe and brought back pieces.
And we have all the experiments that men left on the moon during those missions, functioning as proof.
And we have the LRO taking high def photos now where we can see the actual footprints and tire tracks and the descent stages from previous missions.
Jeeeeez, you have a super computer in your pocket. Being stupid is a choice. Do some legit reading of science magazines and journals. Stop watching homemade videos of a guy in his basement sharing 'shocking news' for clicks..... LOLOL
And if you don't believe your own government and those thousands of witnesses (because you are brain damaged with conspiracy paranoia) then check with the India space program that also has photos of the old descent stages left on the moon from the Apollo missions.
WHY did it take so long to go back? Because we already went a half dozen times, and there was no more reason to keep going back in the 1960's and 70's. But NOW that ice was discovered on the dark side of the moon (1994-1998), we should go back to build a moon base with large equipment like nuclear generators, where we can break down that ice into oxygen for air and hydrogen for fuel, and maybe use the moon as a staging area for Mars !! But that requires an entirely new rocket/lander system that is much bigger.
I KNOW - too many words for you to read and comprehend.
TLDR..... you can remain stupid and just watch dancing cat videos on Tik-Tok all day
