This shows the quality of scientists in the ID movement if they are so confused about the theory of evolution. Evolution does not address the origin of life - it only addresses how life adapts and new species originate due to these adaptations. That is where the title "origin of species" comes from. Otherwise, it would have been named "origin of life".
Scientists do have theories about the origin of life on earth but its not the same thing as the theory of evolution. I will admit that high school teachers often don't know the difference and blur the issue.
When I said that I have not heard a scientist who made that claim, I meant in the entire field, not among IDists. And if you question the quality of the scientists in the field I can list you a pretty extensive list of them. Heck, go to your local book store and you will see volumes of books written by those who suggest ID.
Also, if you can tell me the difference in life and in species, you know more about the subject than I--because I don't think there is a difference in the two. Without species there is no life, without life there is no species. The two are hand in hand.
Are you trying to tell me that evolution says nothing on the subject of the very first species coming to life? Are you trying to say that Darwin does not theorize on how life began or begins?
If you are, I suggest you go back and re-read his books.
