I think there's other life out there but I refuse to look at a vague light in the sky and fully commit to the idea that it's paranormal. I believe aliens could very well exist, but I need proof.
And too often, if people can't explain something from their own limited perspective, then it "must be aliens!". Abduction stories are really suspect too, as they often resemble cases of sleep paralysis or the witness is being coached by the person performing the hypnosis.
If a sighting coincides with multiple witnesses and is actually tracked by air traffic control and/or the military, then it can be taken more seriously, but even then it could still be something besides aliens.
So it's interesting, but I'm not signed on. Richard Dolan is one of the more grounded researchers on this stuff I'd recommend any UFO fans to look into. He also isn't a member of the New Age UFO cliques like Corey Goode (Corey says he's part of a secret space program and he's met giant bird aliens).
