So I have a born again christian family member in their mid twenties who stated with complete confidence that there is a dome in the sky called the firmament and beyond it is where heaven is. She believes space doesn’t exist and rockets just blow up because the bible said so. She is not the brightest and normally I would let this sort of nonsense go but I work in aerospace and have multiple pieces of hardware in space so she is either calling me ignorant or a malicious agent for the devil purposely lying for her so I got pretty annoyed. I can’t find anything about this dome in a google search about religion and I suspect she ended up on a flat-earth YouTube channel that twisted a line in the bible to fit their beliefs and didn’t actually get it from her church. I know its probably hopeless to help her understand how dumb and frankly insulting this belief is but I can possibly talk some reason if I understand the source.
Are there any major or minor religions, christian or other that believe space is a lie and only god is outside our atmosphere?
Like others have said, this is flat earther stuff. A lot of Christian evangelical types question things like the Big Bang and how old the universe/Earth really are, but afaik there isn’t an entire religion with this as a belief.
I used to work at a space museum and we would get Christian folks who would sometimes argue with us over the number that was on the sign telling them the age of our Moon rock, but never that the earth was flat. If that is a thing, it must be new.
