The Wikipedia entry on the swastika says:
It is considered to be a sacred and auspicious symbol in Hinduism, Buddhism, and Jainism and dates back at least 11,000 years.
The source cited for the claim is The Handbook of Tibetan Buddhist Symbols. I searched for "11000" and "11000 years" in it, but this didn't yield any results.
I found a Zeenews article that says:
According to a 'Times of India' report, it has now come to light that 'Swastika' is much older than the Aryans and even the Indus Valley Civilization.
A team of top-notch researchers from several prestigious institutions from across the country have found that the 'Swastika' dates back at least 11,000 years and have traced its spread to western and Middle-Eastern civilizations.
In fact, one of their key findings is that a Ukranian 'Swastika', believed to date back 12,000 years to the Paleolithic Age, may not be this old, said the report.
But it doesn't give any links to the original Times of India article or the report it talks about.
My question is:
Is the claim that the swastika is over 11000 years old backed by scientific evidence?
