OK, there's one important point to be addressed, Mr. Man-in-cape - if that little silo in the museum contains 'the last water on Earth', HOW THE HELL ARE YOU STILL ALIVE?! Man requires water to live! You can't survive without water for more than a few weeks at the absolute most. If all the water on Earth was wiped out centuries ago, all the LIFE on Earth would also have been wiped out, unless you'd come up with an alternate water substitute.
