Looking @ the recent posts abt living on mars and/or moon. IMHO there's no way we humans could be living on those planets in the near future. Yes u've found traces of water on the moon. But how abt continuous O2 sustainability? Food supplies have to constantly be delivered to the planets mentioned above.

Its plausible to start a small base for experiments and what not but to establish a colony up there...I see no gains in doing that.

Anyway back to the original topic...YES the human race can live outer space of course provided with more advancement in space technology.
