If time travel exists, why no one comes from the future?

there is no such thing as time.
Therefore, there is no future or past.
Don't be too hard on your mind, it's not possible to have a device called a time machine.
Time is just an abstract, made-up concept created for human perception.
It's just made so things don't overlap.

Because time travel backwards is not possible, but we can go forward. What happens if we go forward, the real problem starts there. Do we come across a copy of our current states? Can we take our present consciousness into the future? These questions must be answered. Maybe the question of the title should be changed to "if time travel is possible, why is there no one from the past"
