Perhaps they are using some archeotech from a previous race/epoch, they can only maintain it, and use it clumsily. The likelihood of these visits being a (((human agency))) using antediluvian tech is more likely than modern extra-planetary "visitors" of a xenos nature. Archeology offers much "unexplained" evidence of the former, we have almost nothing to suggest the latter RECENTLY outside of statistical speculation.
Fortunately combing through ancient texts and crumbling ruins is far easier than expecting the alphabet agencies to fill you in on recent developments.
