Alien Question for Atheists

[Whateverist]

If you mean they actually bring their own copy of the bible which is word for word the same as ours and worship a man named Jesus believed by them to have been born about 2,000 years ago, not on their planet, but in the region currently known as Israel on our planet .. well .. in that case I'd look around for the person who might be pranking me.

But if they merely believed in a God something like the Christian god, that would just lead me to believe their minds work something like our's, an instance of coevolution across worlds.

No, I'm thinking God would have taken form as one of their own species on their own planet, and had a different name, and didn't die on a cross. But the basis of the story would be the same: That this was considered "God's son" who came to show them the way and spread the same message. He performed miracles while he was there, started the new religion teaching them to love each other, and then was persecuted and sentenced to die a very horrible death for their sins. He soon rose from the dead and stayed with them for a while longer before heading off to Heaven. 

This religion has all the same fundamental principles as Christianity. Meaning they believe in the trinity (father, son, holy spirit), they do have a holy book much like the bible, consisting of writing before this Jesus character came, the story of while he was there which would be practically like the gospels, and further writing after he left. It would have very similar stories with the same principles (especially the story of their Jesus character, as I said above would be practically the same except on their planet) but wouldn't be "word for word" the same, as in like just a copy. And it wouldn't be called "bible" since they speak in a different language lol. They believe in salvation, believe in Heaven and Hell, and their views on morality revolve around love of God and love of neighbor, just like Christianity. They would have different denominations as well, but the basic fundamental tenets would be the exact same throughout, and would be the same as Christianity.

Imagine if that was the predominant belief system in their planet, how would you react?

Then I would assume their mode of consciousness was much like our own, complete with a tendency to project ‘out there’ products of consciousness that are actually
‘on board’.
