It's a Smaller World
Imagine looking through a powerful microscope and discovering incredibly tiny machines taking apart the stuff around them, molecule by molecule, and reassembling the molecules to make exact replicas of themselves. The replicas, of course, will do the same thing. After 20 generations, each machine will have become more than a million. Can they be stopped, or will they take over the world?
This is not some futuristic science-fiction story about technology run amok. This is the world we live in today, where such machines are just about everywhere. Countless millions of them inhabit the gut of every human being. We call them bacteria, and they took over the world billions of years before we humans showed up. We treat them with respect, or they kill us.
Evolutionists aren't sure about the progenitors of bacteria, and we can't repeat nature's experiment. Nature, after all, had the luxury of time, billions of years of it, whereas we mortals must demonstrate progress before our research grants run out. In any case, the simplest bacteria are marvelously complex, with strands of DNA carrying complete instructions for metabolism and reproduction.
