So, with that theology when we see the abundance of life flourishing on this planet, we could simply broaden our view of God to include life elsewhere. If God is the author of life on countless other worlds, it increases our sense of wonder and appreciation.
The second step is this. In Christian thought, humans have a problem in their personal relationships with God. We’re separated from God by our own sin, we need restoration of that personal relationship, and that restoration has been provided by God becoming human. God became incarnate in the person of Jesus Christ and walked the surface of the earth, guided us, and then died and rose again. That restored our relationship with God.
So if there are other intelligent civilizations out there, how has God interacted with them? Have they sinned? Have they needed redemption? Did Christ visit them in their forms? Or did his work here on Earth suffice for all life everywhere?
