Here's a video of L.A. Marzulli, a Christian writer and documentary maker who specializes in End Times prophecy and mostly UFO related material.
He talks about "disclosure" that may be happening soon, and the Pastor who is interviewed, states that the Lord told him “they’re coming” but not from “His Heaven.”
Q, if your position is that the “greys” exist, then that’s something I’m going to have to staunchly disagree with you on. Either way, the video is interesting, so give it a listen.
