It would honestly surprise me to find out in heaven that Earth really was the only planet with life on it. The Bible isn’t specific about that matter so we will never know for sure until we die or we come in contact with something.
And I would not be surprised to find life in some distant galaxy either. I’m completely open to that possibility. My post was meant yo address the curious phenomenon, even on a politically conservative forum, to hold that belief in the uniqueness of Earth is somehow arrogant and backwards thinking.
“The Bible isn’t specific about that matter...”
Well, seeing as the Bible says all the lights in the heavens (stars and planets) were created for us to mark the times and seasons, it actually is pretty specific. If they were created to simply be tools used by us, that kind of rules out them being created to host life of their own.
