Oh, and BTW, it may well be that this relatively calm period is the only period during which your ‘primitive’ life could come to be in the lifetime of the dynamic Universe. If it has taken four billion years to make you, and the Universe you have this physical body in has been around for fifteen billion years, the window of your coming into existence may be closing, and a more restrictive less hospitable Universe may be approaching.
And if we are not here ...how will we know....and why do we care?
