Always doubted it.
Seems like if we could get there in the 60’s, we’d have been there 1,000x since.
There would be outposts and scientific settlements like in Antarctica, etc.
Very much doubt the scientific community would have taken the “been there/done that, one-and-done” approach implicit in the absence of visits since.
And I definitely don’t buy the excuse once offered here that the technology which put us on the moon has been lost, and is irrecoverable.
