Evolutionary Theory Explains Diversity

Are you saying that intelligence may have created the first cells rather than natural processes and then mutation and selection took over from there? Some form of deism?? You have to have life reproducing before mutation and selection can get going, so are you suggesting a mix of ID and evolution? Like some kind of biochemical predestination following natural laws? What about the sudden biological big bang in the Cambrian explosion - no links between all those phyla that appeared and even the few multicellular organisms present precambrian have no connection to the kinds of creatures found in the Cambrian -why? You have to presume that only natural causes can be used to explain these things and then presume that all the many many intermediates that must have been around all happened not to fossilize giving the distinct impression that these organisms occurred suddenly as though created. Well there again, there's no clear transition only the assumption that one led eventually to the other by natural causes and only because of an a priori decision by 'science' that design can't be the answer to any question.So by the definition of 'science' it is already decided that only natural causes and chance can have anything to do with it.What proof do we have that random changes can lead to these incredibly complex systems purely by random chance mutations and natural selection? We don't but it has already been decided, before one piece of evidence was presented, at the level of the definition of 'science'. Instead of defining science as the search for natural causes, we should start with a different definition that science should be the search for the true causes behind all this diversity and not a priori leave out the other possible option -design.
