The lack of seriousness seems more along the lines of "lol China/Russia man" than "lol aliens man". It's rather refreshing to see the DoD entertain explanations beyond "our geopolitical rivals are doing it" - and that includes not making presumptions around humans making and controlling these objects, because if we did know that with any degree of certainty then they probably wouldn't be unidentified flying objects.
