This raises an interesting question: if some time traveler really did tamper with things, what would the evidence look like? Is there anything that could have only happened with knowledge from a now defunct timeline?
Then there’s the horror that it is actually happening and this is somebody’s idea of a repaired timeline.
I don’t think there ever could be observable evidence of a changed timeline. Especially nothing stupid like Marty slowly fading out of existence in Back to the Future.
But tbh, I’m not sure going into the past to change something is actually possible in most cases without creating some sort of time paradox. Interacting with the future shouldn’t cause any problems, but the past is probably set in stone. After all, if I went back in time to assassinate hitler, there is no reason for future me to go back in time to kill hitler since he was already killed, causing hitler to never get assassinated. And on and on it loops.
