What is it, exactly? Is it...

... at the instant of the "Big Bang"? Or...
... when the initial galaxies formed? Or...
... when the earth first settled down? Or...
... when the first microbe appeared? Or...
... when evolution first changed life?

Note that ALL of the arguments between creationists and rational scientists talk ONLY about the last question above. Right off the bat it is readily apparent that this is a false starting point. For one thing, it limits all the speculation to contemplate events on planet earth, as if nothing else existed in the cosmos.
