Many people argue that time travel cannot ever exist, because if they went back in time and somehow destroyed the history which enabled them, they couldn't exist to do it.
But if they don't exist, then they couldn't have prevented their history, so the world would go on just as it had until that person goes back in time, then it would all start again from the same point in time.
We would never know because we would be a time loop until that person grows up, goes back in time, an has never existed again.
I am not claiming time travel will be possible, I am only claiming if it became possible we would never know about it before it became possible.
