However, I think it could happen, but I don't think it should happen. We have one timeline right now which is our own course of history without any time traveling. However, if people were to go back and time and change the timeline and change history, we would have a lot of alternate timelines which could change the entire course of time. Also, let's say someone went back in time to World War 2 and ended having the Germans win the war. We would have an alternate timeline where the Nazis win WW2 but just having that timeline would change our current timeline. Also, we wouldn't be able to change it back and restore history and the current timeline unless we would go back to the exact time and change the events back to normal. Time travel to the past is overall not a good idea.
