Given the number of chances (planets available, etc.) for life to start I don't see how we couldn't have aliens somewhere out there, NOW, THEN, or in the FUTURE.
I don't think we'll ever meet any intelligent ones, however, it took billions of years for intelligent life to develop on this planet. (Yay, dolphins, for making that a true statement.)
