You can breathe and find sustenance in Fort Bridger if you have human skills that have existed for dozens of millenia.

  To be pedantic, evidence indicates that humans have not existed (on Earth) for dozens of millenia. Human skills to breathe and find sustenance below the ocean surface have been common enough for 70+ years. Do you really require that we wait millenia before we try it on another planet?

    To be pedantic right back, you dropped an 'n' in the word and a 'millennia' is 1000 years. Yes, humans have existed on earth for dozens of millennia and in fact we have evidence of early civilizations from around a dozen millennia ago.

    You're missing my point. Although attempting to reach Mars may be wise, Fort Bridger is not an effective analogy. By the time we had reached Fort Bridger, humans had already traveled across huge territories and had already learned to live in incredibly adverse environments. Perhaps we ought to strive for Mars precisely because it's so different than anything we've done before. But as far as existing known human capabilities go, it's not going to be as obviously possible as Fort Bridger.
