Thank you Steph for the welcome note. I have been an atheist for very long now and am glad to have found this group. In my school days, we had a very good text book with quite many chapters devoted to genetic engineering. I still vividly remember adenine, guanine, cytosine and thimane - nucleic acids, the DNA and how the DNA replicates. Ultimately, I never pursued biology, but all of these have had a profound influence on me and my strong belief in science and free thinking.
