Mohenjo-Daro and Harappa Ancient Atomic Wars?? Ancient Alien

Mohenjo-Daro and Harrappa Ancient Atomic Wars. When excavations of Harappa and Mohenjo-Daro reached the street level, they discovered skeletons scattered about the cities, many holding hands and sprawling in the streets as if some instant, horrible doom had taken place. People were just lying, unburied, in the streets of the city. 
And these skeletons are thousands of years old, even by traditional archaeological standards. What could cause such a thing? Why did the bodies not decay or get eaten by wild animals? Furthermore, there is no apparent cause of a physically violent death. These skeletons are among the most radioactive ever found, on par with those at Hiroshima and Nagasaki. 
At one site, Soviet scholars found a skeleton which had a radioactive level 50 times greater than normal. Other cities have been found in northern India that show indications of explosions of great magnitude. One such city, found between the Ganges and the mountains of Rajmahal, seems to have been subjected to intense heat. 
Huge masses of walls and foundations of the ancient city are fused together, literally vitrified! And since there is no indication of a volcanic eruption at Mohenjo-Daro or at the other cities, the intense heat to melt clay vessels can only be explained by an atomic blast or some other unknown weapon. The cities were wiped out entirely. 
While the skeletons have been carbon-dated to 2500 BC, we must keep in mind that carbon-dating involves measuring the amount of radiation left. When atomic explosions are involved, that makes then seem much younger
