they made us use those nerd pens at school

That doesn't make any sense. If humans are "made in God's image" in the sense that they bear a physical resemblance to God, then God is obviously not limited in terms of skin tone, gender, size, or bodily functionality, since those attributes vary enormously in humans. Those variations occur as a result of genetic mutations that prove better adapted to their environment, and there's no reason to assume that evolution on other planets would work differently.

Therefore, either "made in the image of God" doesn't apply ALL humans, or it would apply to other species as well.

More disturbing, however, is your statement about salvation being an issue, given that they (the aliens) wouldn't be "like animals". You ARE aware that sin is a matter of volition, yes? It's not genetic. If it was, then God would condemning people for the attributes that He gave them, which is evil as evil gets. Such a deity is unworthy of worship by any being who has the capacity to worship, as the only excuse for it would be "might makes right", which is antithetical to Christianity. As sin is a matter of choice and not inherent, it's entirely possible for a thinking being to simply not sin- which would logically make "salvation" unnecessary.

So no, what you delivered wasn't a spiritual root canal, but a spiritual amputation- of his frontal lobe. Please stop using your religion as an excuse to stop thinking.

If that was a root canal, I guess I would have given him a lobotomy because I would have told him from line 1 that "aliens" are just demons.

Will he join, I wonder.

But he may not be ready. It doesn't sound like he's even close to being ready. He's tied too much into the world.
