so would it be impossible to detect, because any time evidence was found couldnt the time traveler go back in time to undo the mistake so the evidence never happened?
like lets say for a dumb example, they go back in time, forget a cell phone while they are spending time living in a mud house among ancient egyptians. archeologists of present day excavating find a cell phone buied in the ground thats 2,500 years old and has all the corrosion and transformation to match, this becomes wild news. now the time travelers hear about this, go back in time and make sure to find the cell phone they dropped to undo their mistake, rewriting history for us in the present time so the archelogists doing the excavation never find the phone
is this possible? or would the time branch off into a nother "timeline" so they cant undo the mistake because theres always a timeline where someone figures it out?
