1. evolution says dead things come to life 2. This is an unsupported conclusion. It may be unlikely that something which has never been seen occurs, but it is not a impossibility. Evolution is not based on mutation, it is based on the variance of traits in a population. The environment favors some traits, and not others.
Observation is certainly one tool for the discovery of truth, but there are others, like deduction.
You guys aren't really rigorous enough to prove or disprove anything. Our first conclusion is not, anything never observed cannot happen. Our conclusion is that it unscientific to say that something that has never been observed must be true. Nobody has ever observed an alchemist turn lead into gold. But, there were people who really wanted to believe that lead could be turned into gold, so much so that they actually bought machines that supposedly did so.
