So anyway...
My theory goes along with Steven M. Greer's idea that extraterrestrials are agents of God. I figure if they're another part of the universe, they are not worried about -- for lack of a better term -- wordly pleasures, such as sex and drugs, but rather spiritual concerns. What I mean by that is if then have a connection with God, they maintain their connection to Him by fearing Him. I am not sure if I go along with the idea that extraterrestrials have their own need for salvation, which many theologians propose, simply because salvation is intended for humans. And if extraterrestrials don't have a need for salvation if they don't sin that doesn't negate the possibility that they can have a connection with God since redemption from sin, the way I see it, only applies to humans. Perhaps it could be thought of as a version of the Adam and Eve situation where there was no sin in the garden. I talked to a friend a while back concerning the sin in the garden and he told me that in another universe where there was a version of the Adam and Eve situation, there was no fall of man. Therefore, I don't see sinlessness as something that negates a connection with God because in the Christian worldview, Jesus lived a sinless life and He had a relationship with God. So perhaps the extraterrestrials are a kind of manifestation of Christ and we coud learn something from them.
Hope I didn't ramble too much here.
