DAVID: Same retort: if design keeps you agnostic, who/what is your designer?

dhw: Same answer: if you can believe that a supreme, conscious mind can simply exist without any source, you might as well believe that conscious minds can evolve spontaneously from material sources. I find these two beliefs equally unbelievable.

DAVID: I know, but something designs and it is not chance.

dhw: Agreed. In the context of evolution, I suggest it is the intelligent cell. In the context of the source of the intelligent cell, I can only adopt the same approach you use when I ask you awkward questions about your God and evolution: nobody knows, and we can only guess.

Your answer brings back the obvious question, how did cells find that intelligence which implies the ability for abstract thought?
