That is not how Historians analyze history bro.....maybe that is how they do it in madrassas in Pakistan....but the actual process is different....
Neither you nor me were present during those periods....so,
history is not written merely based on unearthed artifacts......to give it a logical chronology they try to establish a link between those artifacts and modern day religion,culture and practices.....and modern day existing Hinduism provides much of that link.....
For example, since Hitler used Swastika symbol, a thousand year from now, if an artifact with the Nazi Swastika is found in Germany, will it be logical to conclude that the symbol originated in Germany....
NO!
Logical people will try to connect the symbol to the place where it is extensively used and where the oldest such symbol is found....
You're talking about
7000 yrs, but acc. to some study say IVC is close to
9000 yrs old.....so, one can logically understand who 'copied' from whom....
Indus Valley 2,000 years older than thought - Hindustan Times
The Swastika in Belgium was a 7000 year old artifact - please don't tell me that Hindus traveled to Europe before even the advent of Hinduism.
From the archeological evidence it becomes clear that Vedic literature based cultural traditions are better identified with Post Indus Valley Civilization cultural traditions. Let me highlight some of the more pronounced facts in this regard:
• The formation of IVC’s cultural entities can be identified between 3300-1900 BC. Contrarily, the Historians identify formulation of Vedic traditions between 1500-600 BC.
• The IVC’s culture was identified in the Indus Valley (the whole of Pakistan), part of Indian Punjab, Rajasthan and Gujarat. These cultural moorings however do not find an extension into central and lower Gangese Valley in eastern and central Indian plains.
• The decline of IVC traditions started declining after 2000 BC and little of it was identified around 1300 BC. However, the Vedic traditions sustained its development even to the early historic era and shaped into a state-based urban civilization period.
• The Vedic cultural tradition do gel with the chiefdom based rural Post-IVC cultures as they also use rice, horse and iron etc. However, it also displays a distinct difference with the IVC as it was an urban civilization, whereas the Vedic Hindu culture was pronounced for the ABSENCE OF fortified cities, town planning and drainage, monumental art and architecture of burnt bricks, advanced specialization and sea trade, use of seals, weights, measures and script and the custom of burying the dead in cemeteries.
• An attempt aimed at presenting a distorted version of history through identification of fire places as fire -altars, waste pits as sacrificial pits in Harappan era sites and the imaginary reading of Sanskrit legends on Indus seals is nothing but clear fabrication of historical and archeological evidence. Such falsehood was presented in the manner because the presenters believed that India is a Hindu nation and has Hindu culture in continuity from so-called Vedic Aryans and they themselves wanted to see it that way, which however is not supported by evidence.
Please understand that the IVC had nothing to do with Vedic or Hindu culture and IVC is Pakistani heritage and not Indian.
