Do you believe in evolution (the molecules-to-man version) with all of your heart? If so, then you do not believe in design and purpose. You believe that "nature did it", and place your faith in those who teach this. If evolution is truly your faith, then you will feel an emotional response when these ideas are challenged scientifically. Magnificent things happen before our eyes, http://www.youtube.com/watch?v=7AUeM8MbaIk&feature=related , and we must justify them to our beliefs, or our faith will be shattered. If such things happen before our eyes, how much more happens before our microscopes; http://www.youtube.com/watch?v=I9zSe0qmXGw&feature=related http://www.youtube.com/watch?v=Y3Sx-Rj8oV4&feature=related . Do you still believe your life is without purpose? How much more will you have to observe before you allow yourself to ask questions? The more you know about thermodynamics, statistical physics, information theory, combined with observation in cellular biology, the sooner you will question the nineteenth century, nature-did-it approach. Don't let others think for you. Don't be afraid to ask the important questions. Don't let emotions rule your mind, when import outcomes are on the line.
