It seems that researchers have confirmed that “Adam’s Bridge” is in fact an artificial bridge constructed 1,700,000 years ago. Located in the Palk Strait, in the Indian Ocean there is a particular geographical area, a thin strip of land that connects the south of India with Sri Lanka. It is called “Adam’s Bridge”.
Adam’s Bridge is believed to be the remains of an ancient pre-flood bridge. Possibly, the first ever bridge built on Earth.
