Scientists discovered The Bay of Cambay in 2002, 120 ft underwater in the Gulf of Cambay off the coast of India. Measuring 5 miles long x 2 miles wide, carbon dating estimates the site to be 9,500 years old. Amazingly, architectural and human remains are still intact. The discovery predates all other finds in the area by 5,000 years, suggesting a much longer history of the civilization than was first assumed. It's thought the area was submerged when the ice caps melted in the last Ice Age.
