The Bibe says that this sort of contactee information is designed to draw people away from the real Gospel preached the Son of God, Jesus Christ who came to Earth in the flesh to provide Salvation to man by his death and resurrection.
2 Corinthians 11:13-14. For such are false apostles, deceitful workers, transforming themselves into apostles of Christ. 14 And no wonder! For Satan himself transforms himself into an angel of light.
Galatians 1:8 But even if we or an angel from heaven should preach a gospel other than the one we preached to you, let him be eternally condemned!
No more phone calls.......we have a winner.
This person may be writing what he thinks is reality - "aliens" may very well be demons - we know they exist and are NOT our friends.
Seems that many who report alien contact/abductions have dabbled deeply in the occult (think Whitley Streiber).
