Howling:NOT the ninth doctor???

Has anyone put forward the idea that the Doctor who steped out of the Tardis in "Rose", is really the FIRST Doctor, and not the "ninth"? Has anyone established that the Doctor we first saw in 1963 was really the "first"? Making 10 really #2, 11, #3 etc. Might explain River's ongoing joke / brush off, "Maybe when you're older..."
