Did nuclear war wipe out large sections of the civilized world in the third millennium B.C.?

In Ancient Documents INDIA 2449 B.C.
An Indian text recounts in detail how aircraft were used to launch a weapon that devastated three cities. The record is unnervingly similar to an eyewitness report of an atomic bomb explosion. It describes:
the brightness of the blast, the column of rising smoke and fire, the fallout, intense shock-waves and heatwaves, the appearance of the victims and the effects of radiation poisoning. The historical text states,
• An iron thunderbolt contained “the power of the universe.”
• “An incandescent column of smoke and flame, as bright as ten
thousand suns, rose in all its splendour.”
• “Clouds roared upward.”
• “Blood-coloured clouds swept down onto the earth.”
• “Fierce winds began to blow.” Elephants miles away were
knocked off their feet.
• “The earth shook, scorched by the terrible violent heat of this
weapon.”
• “Corpses were so burnt that they were no longer recognizable.”
• “Hair and nails fell out. Pottery broke without cause. Birds
were turned white. After a few hours, all foodstuffs were
infected.”
• “Thousands of war vehicles fell down on all sides…thousands
of corpses burnt to ashes.”
• “Never before have we seen such an awful weapon, and never
before have we heard of such a weapon.
The war zone: the upper regions of the Ganges.

PAKISTAN
Skeletons in Mohenjo-Daro and Harappa are extremely radioactive. Excavations down to the street level revealed forty-four scattered skeletons, as if doom had come so suddenly they could not get into their houses. All the skeletons were flattened to the ground. A father, mother and child were found flattened in the street, face down and still holding hands. The skeletons, after thousands of years, are still among the most radioactive that have ever been found, on a par with those of Hiroshima and Nagasaki.

SOUTHERN SAHARA DESERT
Albion W. Hart, an engineer graduate from Massachusetts Institute of Technology, while traversing a desert in the interior of Africa, was puzzled by “a large expanse of greenish glass which covered the sands as far as he could see.” Not until 50 years later, when he passed the White Sands area after the first atomic test there, did he recognize the same type of silica fusion.

ISRAEL
In 1952 archaeologists unearthed, at the 16-foot level, a layer of fused green glass 1/4-inch thick and covering an area of several hundred square feet. It was made of fused quartz sand similar in appearance to sand at the atomic test sites of Nevada and the Gobi.

BABYLONIA
In 1947, archaeologists on one site uncovered, in succession:
• A layer of agrarian culture
• An older layer of herdsman culture
• A still older layer of “cave man” culture
• Then they reached another layer—of fused green glass!
Lightning may occasionally fuse sand, but when it does, the fusing occurs in a distinctive, root like pattern. Only a nuclear explosion could produce an entire layer, a whole stratum of fused green glass.

Do you think we the people caused the great flood and the ice age?
