    The last sentence in your second paragraph said, “Ninety-six percent of all living things contain carbon.” This is incorrect. All living things contain carbon, because there is no such thing as a non-carbon-based life form.

      It also says carbon is the 4th most AND the most abundant element, this whole thing is ludicrous and repeatedly wrong.
