Actually, I’ve found someone who doesn’t share Harold’s assumption: Francis Crick, co-discoverer of the structure of DNA. Crick, like Harold, recognizes that the origin of life seems almost a miracle, given the intricate machinery of the cell and given how quickly life appeared on the earth after the planet’s formation. Crick cannot agree with Harold, Dawkins, and others who blithely posit that some combination of chemicals must have proved the right one. So Crick offers a different theory: space aliens must have brought life to earth from another planet! This theory is seriously put forth in Crick’s book Life Itself.
