In 58 years of observing the night sky, with 1564 _logged_ observing sessions and thousands more unlogged ones, I have seen a total of 0 (zero) Unidentified Flying Objects. I have logged the Sun, the Moon, 2 total solar eclipses, 1 annular solar eclipse, several partial solar eclipses, many lunar eclipses, 2 transits of Venus, 3 transits of Mercury, dozens of artificial satellites, all 8 planets, 2 dwarf planets, many asteroids, many comets, many aurorae, hundreds of meteors, over 100 double and multiple stars, 238 variable stars, and 660 deep sky objects. In all that time I have not seen a single object in the sky which I could not identify.
Of course UFOs exist. People are forever seeing things in the sky which they can't identify: Venus, Jupiter, airplanes, satellites, meteors, mirages, Chinese lanterns, etc. Like many people, you seem to be confusing UFOs (things seen in the sky) with aliens (living creatures from another world). Not the same thing at all!
UFOs (unidentified flying objects) are only unidentified because the observer lacks the astronomical or meteorological knowledge to identify them. That's why you never hear about UFOs observed by astronomers or meteorologists; they're only reported by people who are unfamiliar with what can be seen in the sky. I've been an amateur astronomer for over fifty years, and have never seen anything in the sky that I haven't been able to identify.
Although life almost certainly exists elsewhere in the universe, the immense distances between stars makes interstellar travel a practical impossibility. No scientist has ever been able to examine a real alien, so all descriptions are nothing but fantasy.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
