In 56 years I have yet to encounter anything paranormal or as proof of extraterrestrial visitation.
The main word in UFO is UNIDENTIFIED. If it is unidentified, that means you are not able to identify it. That's all.
Isn't there a reward of a million dollars to anyone that can provide proof of a paranormal encounter? As far as I know, that money has yet to be collected.
oh wait...
The One Million Dollar Paranormal Challenge was an offer by the James Randi Educational Foundation (JREF) to pay out one million U.S. dollars to anyone who can demonstrate a supernatural or paranormal ability under agreed-upon scientific testing criteria. A version of the challenge was first issued in 1964. Over a thousand people applied to take it, but none were successful. The challenge was terminated in 2015.

The Universe is a strange place. And...BIG.
Chaos can bring any number of conditions together at any given time to show an unexpected result to an observer not expecting a specific result. Weird stuff happens. Consider quantum's spooky conditions. Just cause we don't fully understand the reason doesn't mean it has any significance to paranormal.
