…with the James Web Telescope looking for sources of artificial light to identify potential intelligent life, and the news this week of Perseverance searching for microbial life on Mars it feels like we are getting closer to a major discovery. But what - if anything - would it mean for the religions on Earth if life is proven to exist out there?
Fair points. I originally had the shism in my comment, but decided to keep it simple with a single example.
It might not be enough for you, but I do think the argument that “The entire point of abrahamic religions is to never change.” is so weak, that it can be disproven with a single argument out of many.
I would also not dismiss the importance of Christmas. Might I remind you of the legandary Christmas Truce in World War I? Christmas was so important to these people that it managed to be a bridge between two fighting forces where people on individual points of the front stopped killing each other even for just a bit.
