I firmly accept the idea as a Christian that there is intelligent design. While I believe that God directly infuses an immortal soul into each human being, Catholicism does not deny that the human body could develop or evolve over time. Similarly, God’s time is not our time and so it is likely that the earth is a lot older than six to ten thousand years. The supernova that exploded, creating the heavily elements and the cosmic stuff of our solar system probably goes back at least five billion years. The earth is estimated at 4.54 billion years old. There is fossil and chemical evidence for microbes and photosynthetic organisms as far back as three-and-a-half billion years ago. While we can speak of dinosaurs hundreds of millions of years ago and primates going back tens of million of years, man has apparently only been around in certain forms for a million or two million years. Modern man or homo sapiens sapiens can be traced back a couple hundred thousand years.
I find nothing here insurmountable for Christian faith. Had the first man and woman not fallen, God could certainly have suspended natural laws. If death in some form existed, it might have been as in the Malacandra of C.S. Lewis, an easy transition that does not breech them from those in the body. It might have been as easy as our own going through a door from one room into another. However, at that very moment when the first man received his high calling, he rebelled and preferred the path of the beast (note that Eve is tempted by a devil in serpent form). The friendship with God is forfeited and death is experienced as alienation and fearfulness.
All truth is complimentary. We should not place faith in opposition to true science. Neither should we elevate science to a religion and make presumptions against Christian faith for which we have no evidence.
