Homo erectus used very primitive stone tools – basically just choppers, scrapers and pounders. So how would a primitive human, not even able to start a fire on its own, build an engineering marvel that would challenge 21st century builders?
One and three-quarters million years ago, humans didn’t even have language so they could communicate such concepts as “build,” “straight line” and ‘drop that boulder here.” Language might have developed a million years later, as Wikipedia tells us (although when language first developed is hotly debated, it’s often pegged at about 500,000 years ago): The possible use of rafts during the Lower Paleolithic may indicate that Lower Paleolithic Hominids such as Homo erectus were more advanced than previously believed, and may have even spoken an early form of modern language.
This period of the Paleolithic was in the boundary between the very primitive Oldowan and the more recent Acheulean tool-making eras.
However, these were still very primitive, and humans would not develop sophisticated tools for more than a million-and-a-half-years – until the Mousterian age, some 300,000 years ago.
It’s been called the Adam bridge, the Rama, Sethu (also Rama Setu – setu is Sanskrit for bridge), Ramar and the Hanuman bridge, and Setubandhanam.
The western world first encountered it in “historical works in the 9th century” by Ibn Khordadbeh in his Book of Roads and Kingdoms (c.
AD 850), referring to it is Set Bandhai or “Bridge of the Sea”. The earliest map that calls this area by the name Adam’s bridge was prepared by a British cartographer in 1804, probably referring to an Abrahamic myth, according to which Adam used the bridge to reach a mountain (identified with Adam’s Peak) in Sri Lanka, where he stood repentant on one foot for 1,000 years, leaving a large hollow mark resembling a footprint.

The final paragraph of this tale claims, This information may not be of much importance to the archeologists who are interested in exploring the origins of man, but it is sure to open the spiritual gates of the people of the world to have come to know an ancient history linked to the Indian mythology. Homo sapiens – them back then: they were Homo erectus, a much more primitive version of our species, which existed even before Neanderthals!
