Well, they are what they described, unknown or unexplained.
Taken further, if they are earth based it means some other country has developed flying objects far beyond our known science. Would not be a good thing but there seems no likelihood that is the case. Even when Aurora was being developed by us, there were seemingly enough signs to know it was ours.
Otherwise, it is indeed an extra planetary force. So, what to do. Well, given “their” science is very superior to ours (getting here from light years away) and would conceivebably wipe us out in the blink of an eye if they wanted to, why worry. Remember, when they get here, they will eat the fat ones first. Just watch for the ones with the cook book: to serve man.
Yes in so cal in the 90s or so we had very strange booms going on
Perhaps extra planetary, could also be extra dimensional (parallel dimensions, or timelines), extra temporal (deep past or deep future), spiritual (Good, bad, neutral)
I tend to agree with you. Some people would like to think that this ‘visiting’ race is just a thousand or two-thousand years more advanced. It could very well be that they are 20-million years more advanced. Why would you bother announcing yourself? All you’d do is spook 95-percent of people on Earth.
“if they are earth based it means some other country has developed flying objects far beyond our known science”
A) These “flying objects” might not necessarily even be “flying objects” in the literal sense. Holograms, or plasma phenomenon, could create the appearance of objects that aren’t actually anything solid, which would explain why they don’t seem bound by the laws of inertia or gravity.
B) Just because the Navy says they’re not ours doesn’t mean they’re not ours. Classified stuff is compartmentalized and the Navy may not know about some projects.
