Yes we really went there, quite a few times in the 1970s. We have been again, also several times, with rovers and landers. As for why not humans since then? There's bugger all there to justify the extreme cost (at this time). It's an unpleasant ball made from tiny abrasive dust particles that is more easily explored with robots. The prestige thing is done; until we set up some base there in support of some broader mission (scientific or exploratory) there isn't a reason to send people.

I've put a couple of resources here for you. The first one described the program from a neutral perspective (in line with what you ask - grounded POV to satisfy paranoia): https://bigthink.com/starts-with-a-bang/moon-landing/

This one is for people a little further down the conspiracy pipeline, and it debunks the various things that moon landing conspiracists like to talk about: https://www.iop.org/explore-physics/moon/how-do-we-know-we-w...

Both are worth a read!

Finally this is an excellent jumping-off point to understand the Apollo program in more detail, once you're satisfied that it did happen (if you don't think so, you'll reject the source out of hand.) https://www.nasa.gov/the-apollo-program/

The program itself was really, really, really cool and is worth reading about. A truly enormous achievement involving millions of people and an entire country's scientific and engineering capacity.
