The late Jim Keith was big on warning people that some creepy stuff was really going on ... and you don't need to invoke aliens to explain a lot of the weird stuff.
It's been a while since I read this one, but I don't think that the (possible) existence of intelligent life on other planets is threatening to Christian faith. I do agree with those who point out that a possible evil supernatural entity might pose as a space guy as part of an attempt to deceive pore old gullible humans.
Beckley's pretty sensationalistic, but it's really hard to go wrong IMO when the topic is those MIB.
See you Monday!
