>>13796279Even ignoring arguments that the prior probability (before looking into the details of the cases) for them to be real should be very low, I don't think sightings involving humanoid aliens are exactly at the top of credibility when it comes to UFO reports and they are definitely in the minority. But in the case we're going to take even those cases at face value, I'd assume it's aliens taking this kind of form thinking it's better for interacting with humans or something.
>If they originate from this universe, what advantage would it serve to send a craft leaving behind the most important cargo, the fucking humanoid alien itself. Either way chances are they don't fucking travel around in horse and buggy and need some way to transport themselves around too.The implausible thing here is that for advanced aliens there's some kind of sharp distinction - or rather any distinction - between "them" and "their craft/machines". Given the age of the Universe, it would be an odd coincidence if they'd had just a slight headstart. And by "slight", I mean thousands of years or something, as that is nothing on astronomical scales. In thousands of years mind boggling technological advancement is conceivable, but if we're talking about millions of years it's for sure inevitable. A lot of time for their machines to become smarter than them, and/or them to improve themselves technologically so much that there's nothing left of their original biological form.
Implausible primitivity/incompetence is often a bigger plausibility problem with many UFOs as extraterrestrial hypotheses, rather than implausibly advanced or physics-defying technology.
