I don't think people are, I think they are of the so called evidence that is served up. Well I am for sure.
There is no doubt in my mind there is life out there, there has to be, but are they visiting us or living among us? Hell no.
We live in a technology age with Ring door bells, HD phones, CCTV everywhere, dash cams and people literally on high power telescopes every day and no one has picked up anything that isn't 1960s looking grainy photos. If in this age there isn't one clear photo by chance or luck, at the very least, then I think the odds that we are being visited is slim to none.
The counter to your point is people want to believe so much they will see whatever they want to see, I know
@WillWeEverBeGoodAgain is hugely invested in the idea and wants to believe, so he likely will regardless of the evidence
