Texas Songwriter: "It looks like they are trying to prove intelligent design."
The real question is: did God Create the entire Universe intelligently enough that it could, following God's natural laws, evolve organic chemistry to steadily complexifying simple life, or did God need to intervene with various mid-course corrections to force life back on His track?
My opinion is the former, but am open to legitimate suggestions of the latter.
