Thing is, all these things are mixed; For instance it sure looks like most of the Marfa sightings are indeed headlights on a distant road. The trap for debunkers is that SOME of the sightings may be something else, and, of course, the trap for believers is to believe in everything. You simply have to be critical of everything.
Then, of course, some believers will say "hey, you're just a sceptic", but I'll have to live with that. I'd be as thrilled as most of you for any sustainable evidence of UFOs, ETs, ghosts, Miracles, etc. But I've been disappointed too often. Scientifically minded people may be overly sceptic, but most still keep an open mind. Unfortunately, the believer's camp is a little too full of people who will buy ANYTHING.
