This is how they deceive. Someone asked her how old is Hinduism is. She tells them how old is the word "Hindu".

The word "United States of America" is 250 years old, word "United kingdom" 280 years

Using her logic, Western and English world didn't exist before 300 years. Fair?

How old is Hinduism?

Recently, archaeologists discovered "Baghor shrine". It is a Devi temple with Yantra continuously worshiped by Hindu tribals and their ancestors

Yantra and paleolithic temple dates back to 11,000 years. It is worshiped even today

Jonathan Kenoyer of Harappa Archaeological Research Project(HARP) has been the leading archaeologist of Ancient India for 30 years.

He examined Baghor Kali temple and dated the shrine back to 9000 BC.

He was surprised by "remarkable continuity of religious beliefs in India"

Baghor shrine is a modest temple that only has a stone platform under Neem tree and a triangular shaped Yantra worshiped as Goddess in the middle of platform.

Yet, it has been worshiped continuously since 11,000 years from Paleolithic hunter gatherers to modern day inhabitants

Now, here is my question to all those "experts" who question the antiquity of Hinduism.

Can they name any other currently existing religion in the world which has an active temple that has been continuously worshiped from Paleolithic age? I dare you to give me one example
