Now you are just being silly. I "imagined" it? Get real. A few years ago I think I actually did a thread somewhere here where I posted photos of the second telescopic aerial object I saw, I must have had my small digital camera handy and took several photos of it afocally through the eyepiece. Some evidence I've found suggests it was just a weather balloon while other things support it being an unknown object.

But no one on this earth has "hard evidence."
You don't know that at all. You are not being scientific. You sound like one of the people denouncing old myths of "sea monsters" until about ten years ago, researchers finally caught video of 35-45-60 foot long squid deep in the ocean.
I talk about Webb all the time. Do you know it already has a big hole in one of its mirrors from an impact with space debris? Webb is like an electron microscope tunneling into deep space. If you think it is ever going to catch a picture of a spaceship flying by, you are foolish.
Everything we know about life suggests that life is common in the universe and happens anywhere and everywhere it can take foot. I fully expect they'll eventually discover underwater life on one or two of Jupiter's moons, maybe even vestiges deep under the martian soil.
There are literally millions of sightings of UFOs by millions of people going back THOUSANDS of years, including often simultaneous sighting by hundreds of people at the same time such as in Mexico or the Phoenix lights. You keep arguing what you don't believe, which is fine. But that doesn't change WHAT I SAW, and nothing on this Earth can make instant speed and direction changes traveling at the speed of a jet.
