Time travel

I am a SF fun and one thing has puzzled me over the time: time traveling. I am sure that time traveling is either impossible to be done or we as the human race will never discover it.

Aside from various moral discussions or paradoxes involved with this concept, there is one thing that is obvious. Nobody have come from the future to visit us.

Why?

Because:

1. it is impossible to travel through time.
2. the travelers are very careful not to leave any marks in the past.
3. the human race will gone extinct before the technology will enable us to travel through time.

As option (2) is highly unlikely I am hoping for (1) as (3) is not quite pleasant even if this is the most probable one.
