Yes, Americans landed on the moon, and others sent probes and other garbage. Most recently Israel had an "oops" moment sending a probe that crashed and spread a bunch of things including tardigrades (living water microscopic creatures that can actually hibernate in space endlessly).

There are also the latest Chinese probes, and from several other countries. I think even SpaceX is going to send a Japanese richman tourist to orbit in a couple of years.

Technology in the 60ies was adequate enough, especially within the military and state driven programs of the day. After the space race was considered "over", things slowed and even devolved a bit, programs altered and scraped, budgets cut, etc.

Rocket technology hasn't changed that much, but better materials exist now. SpaceX is successfully reusing stages, something nobody else managed to do before. Computers are far more powerful simplifying navigation. Even live video remains pristine during all stages, unlike before.

Just think about it. A rich American managed to do what 50 years ago took the whole Soviet Union and United States state agencies to pull off.

The moon landing was staged thing is old OLD conspiracy theory that predates youtube, but meh. Look at the Chinese pictures of the moon from the Chang'e probes. If you want to physically be there, just become rich and you have a chance to pay Elon Musk (or some other competitor) for the privilege. Just imagine, spend all your fortune to fly into space... Your contribution might actually help a little develop the space company you backed with your fortune.
