I mentioned this in my reply to another comment,[1] but for reference, this attitude is called Positivism and unfortunately is a common assumption nowadays. Another useful concept is the immanent frame, which is an idea by the philosopher Charles Taylor in his book A Secular Age. The basic idea is that society is increasingly becoming focused on this world (immanent) and losing interest in things outside the "frame", like the afterlife. And so the default assumption becomes something like, "There is no afterlife and only this life matters," even if there is really no scientific or philosophical justification for that belief. 1. https://news.ycombinator.com/item?id=41188210 https://news.ycombinator.com/item?id=41188210 2. https://en.wikipedia.org/wiki/Positivism https://en.wikipedia.org/wiki/Positivism 3. https://ubcgcu.org/wp-content/uploads/2012/08/taylor-and-immanent-frame.pdf https://ubcgcu.org/wp-content/uploads/2012/08/taylor-and-imm...
