Yup. A nutcase. And if he "really" has a PhD in biochemistry, then his gross ignorance is even more appalling. The posted article is rife with factual errors. To point out just one--he claims that the earth has always had a high-oxygen content atmosphere. The transition from a reducing atmosphere to an oxygen atmosphere is well-established by geological and geochemical evidence. And there are similar errors in every paragraph.
Not only is it a PhD in biochemistry ... its a PhD in biochemistry from Berkeley.
