Deliberately, would be my guess, he’s vacillating between preaching and trolling. No one is as stupid as those claims suggest, well, almost no one. Ok, I’m being unrealistically optimistic again aren’t I?
Ok, so that’s a claim that 62 people witnessed something, we don’t know what nor do they, can anyone demonstrate objectively that what they allegedly witnessed were “aliens”?
The link is just a newspaper story relating the same claim? As @cognostic says, can you demonstrate any objective evidence to support the anecdotal claims?
Not much to discuss here really, it wouldn’t take but a few minutes to stir up identical claims that people have seen mermaids, angels, unicorns etc etc…
