i’d say it’s less that people “get very uppity about it” and more that it’s not something that’s particularly relevant. we have no evidence for or against, and the outcome doesn’t really change how we interact with the world
likewise the universe could be entirely chaos and everything that exists in this instant: your memories and understanding of the universe and everything to back it up could just be the current arrangement of things and will be torn apart in the very next instant
but it’s not really a useful position to form conjectures from: if it is, it doesn’t matter what you do; if it isn’t, then you should act as if the universe will be here and that your memories are valid
it will truly be a great day for humanity when our smart microwave can display accurate time derived from literally differences in things travelling the speed of light and atomic decay with redundant backups and systems designed to withstand nuclear war
a great day indeed
