I hope one day we figure out what are those camera/visual/aerial artifacts.

Those aliens are both the stealthiest and least stealthy entities. Show yourselves if you want to, or wtf are you guys doing if you want to stay hidden?

The funniest thing would be someone with an iPhone to finally be able to make a 60 fps, 8 bit colors, crisp video in full daylight of an obvious alien UFO saucer, and have Apple use that to advertise their cameras for the next 25 years.

These high quality vids have existed for a long time, see [1] for examples.

Of course, that doesn't necessarily mean it's alien craft.

iPhone's are designed to take close shots, they don't have optical zoom so zoomed in or distant photos are very blurry. Trust me I have tried taking photos of lots of things that are clearly seen in the distance only to look like a early 00s webcam photo when I take a picture with my phone.

AFAICT, the quality and resolution of these supposed alien UFOs hasn't improved a lot since the 50s.

I don't believe that's accurate. I linked a "documentary" elsewhere in this thread that contains purported UFO footage which is high quality in an absolute sense and much better quality relative to anything in the 1950s.
