As somebody mentioned here, it's incredibly expensive and difficult to send human beings on space voyages. The time and distances involved for true interstellar travel are daunting. (Robert Heinlein had an interesting solution in Orphans of the Sky.) I've heard pure speculation that if any extraterristorials ever reached Earth, they must have used some inter-dimensional method that is not linear point to point travel. The technology of that, if it were possible, is unknown to us.Unless there is a good political or economic reason to go, we won't.
We stopped going to the moon because we beat the Soviets. After that, there was no political will to go.
Now that commercial space is opening up, there is more pressure to go back, hence the Artemis missions.
Of course, that begs the question of why aliens would bother with their brief appearances in places like West Virginia or New Mexico.
