the problem with it is, if you ever talk about an intelligent designer or a God, it goes into the realm of pseudoscience an religion. These claims are non falsifiable, and firmly outside the realm of science. There is a very well established evolutionary theory of the origin of life, and it states that as the climate of the early earth changed, it spawned new molecules (RNA, DNA, etc)which had the remarkable capability to self replicate. Over time, these molecules could have begun to get more efficient due to competition for limited resources. This chain could continue until all opf the diversity on earth is developed. Most importantly, this theory has true evidence that has been tested, replicated, and has held up.
sorry, but science needs evidence
