The physical Universe is just that, unthinking and unconscious entities more mathematical than real.  Somehow, however, the juxtaposition and intermixing of these physical things chances on life in the form of individual cells, such as bacteria.

     With Eons of time and mixing, pushing, shoving, heating, and cooling multicellular organisms form.  And, with more Eons of time, plants and animals form.

     It would seem that only with DNA creatures does consciousness arise.  Finally, rocks and plants are perceived by consciousness, just as 0's and 1's become a movie during a computer simulation.

     This is why DNA is so important!  And, DNA is weird.  It has been found to absorb photons and trap them.  Recently, it has been discovered that at the moment of conception a flash of light is produced, a flash visible to the naked eye.
