> The thing to notice is cameras have become much more prevalent and much higher resolution, but "UFOs" in pictures haven't.

Get out your phone, and take a picture of your hand. Its very close, and you'll get a great photo.

Now, go outside at night, look at the beacon on top of a crane in the distance, or a plane landing a few kilometres away. Try to take a photo of it with your phone camera.

We have great cameras, sure, but not everyone is carrying a 300mm lens in their pocket
