UB is the fastest person ever timed for a 100m or 200m track race. is he the fastest human ever alive? We will never know.
At present no human has ever travelled to Mars and so, at present no human has ever landed on it.
The fastest time ever to run a mile is 3 minutes 43 seconds. Hope this helps you!
