We're not advanced enough to understand "aliens".
I believe that our tech isn't sufficiently advanced to understand any of this tech even if it's proved. We're just not that advanced at this point much like if someone had a time machine and could take an aircraft back say 100 to 200 years ago. They could say saw someth9ing but not really describe it other than "something flew like a bired only bigger and faster.
If "they" are out there, they might be amused at our efforts to understand/describe in a rational and scientific way to explain "the aliens" flying/travel.
The "we don't know" category is larger than the "we know" category at this point.
I remind myself of "one man's tech is another man's magic".
