That is, the germs or viruses which cause these diseases can survive only in living human bodies or well-equipped laboratories. Well-known examples include measles, pneumococcal pneumonia, leprosy, typhus, typhoid fever, small pox, poliomyelitis, syphilis and gonorrhea. Was it Adam or Eve who was created with gonorrhea? How about syphilis? The scientific creationists insist on a completed creation, where the creator worked but six days and has been resting ever since. Thus, between them, Adam and Eve had to have been created with every one of these diseases. Later, somebody must have carried them onto Noah's Ark.
