Where “Good Morning” came from

Here is my theory of where “Good Morning” came from:

In the desert, out on the west coast of India, one of the standard morning greetings, in translation, used to be, "Have you had a good breakfast?" The words used, with a questioning sound were "gûr-mäni?" Gûr is the common north Indian word for jaggery. Mäni is a pita-type of coarse patted, flatbread made from pearl millet, or bäjrä that is made on a low fire. My theory is the English "Good Morning" comes from “gûr-mäni" and never mind what the lexicographers, and language-historians of English say. What do they know any way?
