Re: @tfb - @Mike 137 - Life, but not as we know it?
The formation of DNA and cell division I guess is the basic definition of "life as we know it". Does life need to meet our arbitrary qualification for it? Life takes another step in level when it becomes sentient, the threshold for this is somewhat fuzzy.
I'm open that the development of something other than organic cellular life forms could grow and that a sentient state could exist in some form other than an organic cellular platform.
