Well, I am. It turns out to be a long history; carrots have been eaten as food by humans for a long time. This page is a museum of information about carrots, including their history. Special attention is paid to the fact that carrots are not just orange; they come in a rainbow of colors. Orange is a fairly recent carrot color. There are links to references supporting the text, also.
Many thanks to my friend John Desmond for turning this one up (so to speak) and bringing it to my attention.
