If the definition of the present is that it a moment in which the future is not yet fixed or definite. Then travelling into the past would create a new present moment. It would dissolve the future you had left behind or the past would change as you interacted with it. So a universe with time travellers would have many present times and multiple different pasts. That is assuming the changes propagate as the time traveller experiences them.

    Time is interesting. It's a local phenomenon. Our time is not the same as another planets time. Even the ISS travels through time at a different rate than us on the ground. And light experiences everything in an instant. It's like we're all in our own little pockets of time.
