Purpose vs Purposeless

For the theist, a Creator is the explanation for all.

For the atheist, no explantion is possible, for each bit of life merely expires to nothingness (organic to inorganic) -- no matter, no consequences, no purpose. The closest explanation for them is, "life is" with a bit of speculation about some remote time when "life wasn't" and some mystic brew that caused inorganic to become organic life.
