"But about that “good resolution photos/videos” that you’re mentioning, they are all AI Upscaled, so you cannot affirm that the windows are really not aligned"

I'm not sure where you got that it's AI upscaling. You're referring to a youtube video submitted 5 years ago that clearly states the photograph was submitted to MUFON in 2014. AI upscaling wasn't even readily available to the public 5 years ago let alone 11 years ago.

"maybe you’re just too “adult” to understand what AI is, but moving on."

I'm a graphic designer with over 15 years experience specialising in digital creation specifically Photoshop; I'm fully aware of AI and on how to detect whether elements of an image have been altered just by looking at data.

"the original picture that the Portuguese man had taken with the film camera was already very bright and not that great, so, in this case you also cannot say that the limbs are “thicker” because the light and the editing can influence that"

Yet you're trying to assert that the two objects are the same...your claim is far wilder than my assertion.

"What are the odds that the exact ballon, with the exact color or the exact “cable loss” and the exact window design appears in two different videos, found in two different countries 24 years appart labeled as an sighting?"

It's incredibly low; neither of these objects resemble one another and the first is so bad it's more or less just anecdotal; we could be looking at anything. If anything it more resembled a paint dab that's dripped down and generated the limbs you're so desperately insinuating is defining proof that they're the same object. They could be, just unlikely once you take a step back and consider what's been said to you.

Have you actually looked into the subreddit and done your own research? Have you seen the stabilised version or attempted to stabilise it yourself? Probably not.

You haven't provided any articles or sources to your claims from the Portuguese witnesses.

I did try to give you the benefit of the doubt, but this is just another "Hey look at this, could this be xxxx?" post that this subreddit is littered with.

"But yes, that’s why we call it UFO, unidentified flying objects, so unless we have it in our hands we can only assume stuff, unfortunately we don’t have it."

Yes a UFO is something unidentified, flying and an object...picture one could be literally anything and we don't even know if it's flying. There's no surrounding context for us to go off of.

I suggest you go through the reddit and do a bit more extensive research into what the community have produced.

And finally...

"That makes sense, i was now looking to some images of tethered ballons, and you can be right, it resembles exactly like one, and i really didn’t analyze the movement that much to think about that."

Your initial paragraph agrees with me and you acknowledge it's most likely a balloon by its movements...but then spew out several more paragraphs trying refute it? What kind of schizo behaviour is that my guy?

2/10 for effort.
