“As a Christian… Do you think/believe that there is life outside Earth?”

Christian response,

There is life “outside” the Realm of Time/physics. Human life on Earth is exclusive, temporary. The mysterious “life” observed by some and referred to as “alien” results from an interaction between the Realm of Eternity (the spiritual realm) and the Realm of Time…a glimpse….a momentary infusion/interaction of the eternal with the physical, nothing more. Jesus explains that His Kingdom, His servants and His warriors (the angelic), are not of this temporary Realm of Time.

The spiritual war between the demonic and the Heavenly does interface with the physical from time-to-time…these are the “alien” encounters observed by humanity (Ephesians 6:12). These encounters will most likely increase as Time approaches the Tribulation; the Millennial Kingdom; Judgment.
