Eden, if you can believe any of the above, you can just as well believe in God and the Bible. These actually make more sense. Think of DNA as a manual of how to build a cell/organism. In time minor changes (or mutations) could occur, changing the manual. Major changes (or mutations) would kill off the organism. The manual, as information, cannot arise by itself, from organic or inorganic matter. You need someone to write the manual and its applications.
So how would the sexes originate? The manual needs to be written (programmed) for that. The question is: Who wrote the manual? What the evolutionists are saying: Archaea (basic or simplified organisms) > Eucharyotes (complex organisms) > colony formation > multicelluar organisms > male/female organisms. How would they prove their theory? How would they be able to demonstrate such changes? Archaea > male and female mammal (and everything in between). So far they have been unsuccessful. Wishful thinking if you ask me.
