I think not....
This clip states that a lost civilization has been found in India, but I'll let it speak for itself....

'Lost' India civilization may be 9500 years old: minister
NEW DELHI (AFP-Jiji) Indian scientists have discovered a lost river civilization dating back to 7500 B.C. off India's western coast, a senior Indian Cabinet minister said Wednesday.
The discovery would suggest the world's oldest cities were built about 4,000 years earlier than is currently believed. "The findings buried 40 meters below the sea reveal some sort of human civilization, a courtyard, staircase, a bathroom or a temple or something," said Murli Manohar Joshi, minister for human resources and also ocean development.
The earliest discovered human civilizations in the subcontinent are the sites of the Harrapan and Indus Valley communities, which date back to 2500 B.C. The world's first cities are commonly believed to have appeared around 3500 B.C. in the valley of Sumer, where Iraq stands, a statement issued by the government said.
The marine archaeological findings have been made by a joint exercise conducted by the National Institute of Ocean Technology and other Indian ocean development and archaeology institutes in the Gulf of Cambay region, off the coast of Gujarat state in the Arabian Sea. Objects such as pieces of construction material, artifacts with rectangular holes, fused objects, pottery, beads, broken pieces of sculpture, a fossilized jaw bone and human teeth and a cut wooden log have all been retrieved from the site. Carbon-dating and other methods have dated the finds to around 7500 B.C.
Acoustic imagery has revealed a river stretch of 9 km along which all the objects have been found, as well as built structures protruding from the seabed.
Previously it was accepted that the Indian civilization began perhaps as far back as 500,000 years ago, the India we know starting in Neolithic times perhaps as far back as 7000 BC with the Mehrgarh, then into the Harappan civilization, that was invaded by the Aryans around 2500 BC, and countless invaders over the years, with the country developing and evolving, or de-evolving, depending on your point of view, into modern times.
If in fact an unknown and truly advanced civilization has been discovered that's older yet, circa 7500 BC, it pretty much throws a monkey wrench into that. Of course to many of us, it was never accepted. Instead we believed that India was in fact home, or one of the homes, of a truely ancient civilization(s). Not cavemen, Not hunter gatherers who somehow by some miracle became farmers and city dwellers almost overnight. But, instead a civilization equal to or greater than our own. Not the same of course, but on a paralell.
There is a saying, I don't know who said it, or where or when, that China was civilized when Britons were still living in caves painting themselves blue. But, I have read that China was young when India was already old. Meaning I guess that India was civilized when China was...well you get the idea.
I personally think that we moderns, who are really little or no different than those who lived in 7500 BC and before, are mutations, (though due to pride and ego we prefer to use the word evolution), of those who lived and populated those advanced, antidiluvian or prehistoric advanced civilizations, (whether they were Homo Sapiens, Neanderthal, Homo Erectus, or whatever), one of which may have finally come to light.
Actually anatomically modern humans have been around for something like 200,000 years. They say that 50-60,000 years ago, what the anthropologists call behavioral modernity, which is to say music, language, etc. may have just happened one day, due to some sudden event or mutation, (that word again), or possibly as a culteral evolution, a gradual accumulation of knowledge, culture and skills over thousands and thousands of years. Of course that's the anthropologists guessing, unless the've found a time machine, or some other way to verify.
But the point is that if humanity has been around that long, and more or less the same as us, let's face it, the world as we know it has only existed a hundred years or so, when I was a kid in the 50's there was almost no difference from when my parents were kids in the 20's or 30's, and the 20's or 30's were very little different than the 1800's, or even the 1700's. Take away the computers and we'd slide backwards pretty quickly. Anyway as I was saying, if humans have been around that long, 200k, 75k, 10k, 7500 years, who can say how many civilizations have been and gone? Back to where I started, it seems that such an advanced civilization, in India, has been found, that predates what are accepted as the earliest civilizations, the Mesopotamians, Sumerians, and Egyptians. Which are only now, starting to be considered older than previously thought.
So Mote it be... Or put another way, Later.
