If that has happened 6 times, how long does it take for and how does the earth recover?
in our terms an eternity- in terms of the universe, the blink of any eye
put it this way, The All Whites wouldn't win the world cup in that amount of time
(Ok that doesn't make sense..)
Bill Bryson in his book "a short history of nearly everything*" says Human's have been on Earth for 0.0001 per cent ofthe total history of the earth or if the universe was a man with outstretched arms from left to right, with the
Big Bang on the left hand then Homo Sapiens have been around since the last 2mms of the quick on the right hand-
um yeah, not sure if i gave that metaphor justice
* great read btw
