Non sequitur? Oh that's nonsense. If something behaves in a way our laws don't support, we'll say they violate those laws. But that doesn't mean our laws are correct. They're as good as our science and collected data allows.
I think you're completely missing my point. I'm saying that if the laws of Universe allow something to happen, then it is very possible that we can figure it out, at some point. If these vehicles are functioning within the physical laws of the universe, someone learned those new things that made it possible. Why is it more likely to be "someone" we have no evidence even exists over "someone" that we have lots of evidence does exist?
