Sorry dude, you must have missed latest development in IVC. The most scientific analysis of their language puts it nearer to Sanskrit. The other contender is Tamil language which again is the part of Hindu heritage. Om was there in the IVC seals, then how on earth you claim that it was not? Your claim is so funny, first you say IVC did not know Rig Veda then say they might have recited a small part but they were not Hindus? No where you address my questions though. Also, how do you know descendants of IVC people live only in present day Pak and not in India? you got proof or did some IVC person time traveled to inform you specially? After IVC, did that whole area lay empty till muslims came and settled? in that case, you can't claim that present day people are IVC descendants. Or, if people were present, which religion they belonged to?
You see, when you start with a conjunction to suit your propaganda, and then you try to throw some jargon and made up facts to prove yourself right, you look amateurish like you are looking like now...
The language of IVC has not been deciphered so far. How would you put its structure nearest to Sanskrit if you can not even read what is written. Have a heart, please. I never said that IVC people recited Rig Veda. When Rig Veda was not present at that time how could they have recited it. OM is a Sanskrit word as written in Sanskrit. What was discovered was certainly not OM. Large majority of descendants of IVC people live in Pakistan. Only a small quip live in India as the IVC spread was also in parts of Indian Punjab, Rajasthan and Gujarat. Around 4-5% od the total Indian population, if I am not exaggerating it a bit. The people of IVC continued living in the area and the religions they followed, please read the first post.
