In addition to what John said, it should also be pointed out that Joseph's argument is that abiogenesis could only occur by chance alone. If that were true, he would be right. In fact, however, abiogenesis occurred because of specific non-random mechanisms. Such mechanisms can produce a result that might seem highly improbable by chance alone, but if in fact that is the only result they can produce, the probability of getting that result is really 1.
