I have (probably) never seen one and I don’t remember being ever abducted by one.
Still, it makes sense that they are around and all the evidence is hard to ignore. Additionally, I ran into a web page today that has lots of video footage of testimonials of rather credible witnesses. What I like about these witnesses is that they just report their observation and don’t try to mix it with their own interpretations and opinions.
Take a bowl of popcorn and a beer because some of that stuff is long…
