How Else Could It Have Gone

How far back do you wish to go? Could the universe have failed to Big Bang? Could the galaxies have all failed to form? Could the sun have failed to be born? Could the moon have been to small? Could it have failed to form at all? Could life have been still born? Could the asteroid have passed us by? Could Eve have been to shy? Could Neanderthals have won the day. Could the Vikings have held sway? Could Columbus been sunk at sea? Could the Pilgrims have stayed at home? Could the Revolution have failed in vain? Could Marie Antoinette have kept her head? Could the South have won the war? Could the Titanic have stayed afloat? Could Nazi Germany have prevailed? Do infinite realities indeed exist? Has everything in fact occurred? Where does it all go from here?
