Why for long India remained without a 'HISTORY' ?

1. Why is it that Indians produced great works of Art, Literature, Medicine, Mathematics, Linguistics etc but no such work in History (in the European sense of the term) till Kalhan's Rajatarangini?

2. Should we presume they had no history?

3. Or, they had no sense of history?

4. Is the SENSE of TIME in India same as that in Europe?

5. Is this,  the  sense of time, to explain the absence of  'HISTORY BOOKS' in India?

6. What are the sources of myths?
Do they -- myths-- also serve as Indian version of History which is European in it's spirit?

7. Are History, Purana and Itihas one and the same?
