I like the rebranding to UAP (unidentified aerial phenomenon) though.
There is a normal reason for that though.
UFO refers specifically to a flying object.
UAP refers to any phenomenon.
A light in the sky is not necessarily a flying object.
Your Frisbee remark apart from childish does not take into account both the evidence and the sources.
Not really.
It points out exactly what UFO/UAP means.
It does not mean aliens, it simply means it isn't identified.
From what I have seen so far, including from the military and government sources, there is no reason to conclude they are aliens or really anything special.
There are lots of hard facts and compelling evidence for both the world being flat (or at least, not spherical) and for the reality of ufos (and by that I mean flying saucers and related flying machines) over the past century. The evidence hasn’t changed - advertising and media has.
Well you are right about one part, the evidence hasn't really changed much. There is no significant evidence supporting either of those claims.
But with youtube, people can market it loads more to pretend both of those positions are supported by evidence, even without any.
Evidence and facts are quite easily ignored, and this is what affirmative bias (confirmation bias) is all about. Regardless of what you want to believe, it is embarrassingly easy to ignore everything that contradicts it and only see what you want to see. More facts and data are not required, in flat earth research nor ufology, rather it is the skills necessary for objective research that are conspicuously lacking.
And I certainly agree with pretty much all of this.
Those who believe in aliens will take almost any footage where it isn't easy to identify what is there, and conclude it must be aliens, even though there isn't really anything to support the idea it is aliens.
Those who believe Earth is flat will take almost anything that they think can support the idea that Earth is flat (or not round) and use it to claim it shows beyond any doubt that Earth is flat/not round.
Neither seem to carry out the objective research necessary to exclude other possibilities.
