Another study explains the origin the structure due to longshore drifting currents which moved in an anticlockwise direction in the north and clockwise direction in the south of Rameswaram and Talaimannar.

The sand was supposedly dumped in a linear pattern along the current shadow zone between Dhanushkodi and Talaimannar with later accumulation of corals over these linear sand bodies…

This is, of course, between 840,000 and 800,000 years BP, not 1.7 million years ago.

If the earlier Homo erectus had vocal communication, it was probably limited to simple sounds paired with gestures. It wasn’t a complex language that a bridge builder would have needed.

The Times of India had a story in 2002, noting: Hanuman bridge is myth: Experts Eminent astrophysicist J V Narlikar, when contacted in Pune, said he had seen reports claiming about the mythical bridge, but there was no evidence to suggest that what had been located had links with the bridge mentioned in the Ramayana. Claims that it was part of Atlantis and Lemuria quickly followed.

“There is no archaeological or literary evidence to support this claim,” eminent historian R S Sharma told The Times of India in Patna. Nor had human habitation occurred 1.75 million years ago,” Sharma, an acknowledged authority on ancient Indian history, said. They’re of the sort, and has been trying to distance itself from any such ludicrous claims for more than a decade.

Let’s start with the alleged age of the “bridge” in this wacky tale: 1.7 million years (the age of the rocks on the periphery of the tombolo, by the way, not the actual shoals or corals). They came out of Africa about 1.85 million years BP, or possibly from Asia.

These were the first humans to engage in social behaviour that led to the change from scavenger to hunter-gatherer over many millennia, but they were still very primitive, grouping together in small bands and extended family units, gathering plants, fishing, hunting and scavenging.

However, that was before the internet existed to let wild and unsubstantiated conspiracy theories go viral.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.another group of geologists propose crustal thinning theory, block faulting and a ridge formed in the region owing to thinning and asserts that development of this ridge augmented the coral growth in the region and in turn coral cover acted as a `sand trapper’.Back in 2002, there were unsuccessful attempts by actual scientists to debunk the “ancient civilization” theory and inject some needed common sense and real science into the discussion.

During the Paleolithic, humans grouped together in small societies such as bands, and subsisted by gathering plants and fishing, hunting or scavenging wild animals.
