If anyone wants some sf on the subject, I recommend Leiber’s The Big Time and “Try and Change the Past”.
They’re both based on the same premise. The timeline is changeable but highly resistant. Humans can’t change it (that’s the short story) but there are two superhuman sides (called Snakes and Spiders, but never seen onstage) which recruit humans who are willing to be cut out of their timelines just before they die.
