They literally admit to you that they have no clue how to travel to the moon now.

You are saying this two days after the Artemis mission launched. Do try to keep up.

The people who told you they went in 69 are the same people telling you they can't do it now.

The people who ran the Apollo programme in '69 are all retired or dead now. The people who are in NASA now are saying that they are on track to go back by 2025. Personally, I doubt they'll make it that quick, due to budgeting constraints and lack of the "Can Do!" spirit of the 50s and 60s, but I could be wrong.

While NASA has lost a lot of unwritten institutional knowledge since the early 1970s, and picked up a lot of bureaucratic deadwood of the sorts that caused the space shuttle Challenger disaster, the idea that they have "no clue" how to get to the moon is bullshit. It's just rocket science.

In 2022, we literally have no clue how to build a new DeLorean because the parts are all gone, the tooling is gone, and the blueprints were deliberately destroyed to prevent competitors stealing the design. Does that mean that DeLoreans never existed?

We can't build an Apple II computer in 2022. The chips aren't available, the parts are gone, the tooling and moulds to make the computer have been destroyed. Nobody makes 5.25" floppy disc drives any more, and its not economical to tool up to make more. Even if we could find the blueprints, and we probably can't, we'd have to tool up from scratch, and the techniques used in 1977 to make the Apple II are obsolete or not cost effective any more. By your logic, that means that the Apple II was a hoax.
