The Darwinian vs. God Contest

One day a group of Darwinian scientists got together and decided that man had come a long way and no longer needed God. So they picked one Darwinian to go and tell Him that they were done with Him.
The Darwinian walked up to God and said, "God, we've decided that we no longer need you. We're to the point that we can clone people and do many miraculous things, so why don't you just go on and get lost."
God listened very patiently and kindly to the man. After the Darwinian was done talking, God said, "Very well, how about this? Let's say we have a man-making contest." To which the Darwinian happily agreed.
God added, "Now, we're going to do this just like I did back in the old days with Adam."
The Darwinian said, "Sure, no problem," and bent down and grabbed himself a handful of dirt.
God looked at him and said, "No, no, no. You go get your own dirt!"

Denton A. Cooley

Born 22 Aug 1920. Dr. Denton A(rthur) Cooley is an American surgeon and heart-transplant pioneer who was the first to implant an artificial heart in a human. In 1960s he performed delicate surgery on the hearts of infants with congenital heart disease, and was the first surgeon to successfully remove pulmonary embolisms. On 3 May 1968, Cooley performed his first human heart transplant. On 4 Apr 1969, because no donor heart was available for a dying 47-year-old patient with diseased heart muscle, he implanted a mechanical heart made of silicone as a temporary measure. The experimental artificial heart was used for 65 hours, and was removed when a human heart became available.«
