These two side-by-side statements, alone, suffice to seriously degrade this article's credibility in my eyes. In fact, I'd say that the article is deliberately trying to misrepresent the facts and thus awaken doubts.
From the very beginning, Willard F. Libby (who was later awarded the Nobel Prize for his efforts) understood that the C-14 had to be (more or less) constantly formed (in the upper atmosphere, by cosmic ray bombardment of Nitrogen).
