So we have scholars accepting two different paradigms, both of which complement each other and should therefore have been treated as two parts of a whole: on the one hand, a widespread network of archaeological sites of a vast, highly-developed civilization (the Harappan civilization) lasting over thousands of years, which has allegedly left no literary records at all although it had a writing system; and, on the other, a full-fledged developed culture and civilization (the Vedic civilization) which has left a vast and detailed body of organized literature (unparalleled by any other known civilization of the same period) although it had no system of writing at all, but which has left absolutely no archaeological traces behind, both located in more or less the very same area!
