I am lacking something here. How can something destroy complex life on
both sides of a planet but leave the single-celled life unkilled? Do
these explosions last for a whole day of gentle frying, or does the
radiation flash right through the earth? Forrest, are you saying that
single-celled life just starts right up again every time? Not that
that seems impossible since Kauffmann, but isn't there evidence that
microbes from billions of years ago are related to us (i.e., evidence
of a continuous line of life since then)?
