My right to be a skeptic about the jellyfish

I am a child of the 50’s. I grew up on black and white sci fi and was mesmerized by the idea of UFOs. I remember when the USA wouldn’t even admit that project Blue Book was a thing. When CE3K was released I thought “oh boy, now we’re getting somewhere” but I think I was wrong. Bottom line is that if all this is true and we are being visited/occupied by things not of this earth, that will be the biggest event in the history of mankind since Day One. And if you want me to buy into that I will doubt, doubt, doubt your evidence till I am 100% +++ convinced and you have absolutely proved that all other explanations are wrong.
