The actual reason why the indus valley civilization is more indian than pakistani is because of the legacy. The same religious rules are practiced among the hindus even today. Just because of some minor differences in geography does not mean that our identity with the IVC is not ours.
Similarly, the many pakistani muslims like to associate themselves with the muslim invaders who are of Arab origins. Meaning pakistans legacy is more inclined towards the arabs than towards indian hindus. Geographically the IVC is pakistani. But, socially, religiously and spiritually IVC is truly indian.
Humans can trace themselves to AFRICA. But thats not the point.
The regions between india and persia have seen too many wars.
The persians invaded. the greeks invaded. then the muslims invaded. The region around the Indus has seen 2500 years of wars ever since the first greek and persian invasions. The invasions of chengiz khan and the huns were as catastrophic as the muslim invasions.
There is no guarantee that the original people of the Indus have actually survived. Maybe they were pushed back towards the gangetic plains or probably pushed towards extinction. Maybe a growing population pushed them away from the Indus in search of new pastures. A flood might have done the same too. Who knows?
Their lineage is lost, only their legacy survives. And thats what India is a part of.
Nothing is known about the religion, language or culture of the Indus Valley people. So relating them to Indian culture doesnt make sense.
The actual reason the Indus Valley is a Pakistani civilisation is because Pakistanis have been living in that valley for 1000s of years. Yes invaders have come and gone but
Pakistanis have always been native to that land.
I cant help if you want to fabricate a load of absolute nonsense about Pakistanis being alien to their own lands. I see that you listed floods, wars and extinction in a desperate attempt to associate the Indus with India. Very convenient theories.
I dont see why Islam has been brought into this. The history of Pakistan belongs to Pakistanis regardless of what religion they followed. Indus Valley religion, Buddhism, Hinduism, whatever.
Being Muslims now doesnt give Indians the right to grab Pakistans non Islamic history. And the claims of random Muslims who have never heard of IVC dont void any of my arguments.
And since you love to quote Pakistani Founders, here is a quote from Jinnah:
"We are a nation with our distinctive culture and civilization, language and literature, art and architecture, name and nomenclature, sense of values and proportion. Legal laws and moral codes, customs and calendar, history and traditions, aptitude and ambitions; in short, we have our own distinctive outlook on life and of life." -Quaid-e-Azam
