Aren't the explosions and events described in the ancients Indian texts proof of ancient nuclear weapons?

Question

"Gurkha, flying a swift and powerful vimana (fast aircraft hurled a single projectile (rocket) charged with the power of the Universe (nuclear device). An incandescent column of smoke and flame, as bright as ten thousand suns, rose with all its splendor.

It was an unknown weapon, an iron thunderbolt, a gigantic messenger of death, which reduced to ashes the entire race of the Vrishnis and the Andhakas.

The corpses were so burned as to be unrecognizable. Hair and nails fell out; Pottery broke without apparent cause and the birds turned white.

...After a few hours all foodstuffs were infected...
...to escape from this fire the soldiers threw themselves in streams to wash themselves and their equipment."
ؤؤ The Mahabharata

"(It was a weapon) so powerful that it could destroy the earth in an instant A great soaring sound in smoke and flames And on its sits death..."
ؤؤ The Ramayana

"Dense arrows of flame, like a great shower, issued forth upon creation, encompassing the enemy...
A thick gloom swiftly settled upon the Pandava hosts. All points of the compass were lost in darkness. Fierce wind began to blow upward, showering dust and gravel.

Birds croaked madly... the very elements seemed disturbed. The earth shook, scorched by the terrible violent heat of this weapon. Elephants burst into flame and ran to and fro in a frenzy...
Over a vast area, other animals crumpled to the ground and died. From all points of the compass the arrows of flame rained continuously and fiercely.
ؤؤ The Mahabharata

Don't these accurately describe the effects and events caused by a nuclear explosion?

Answer 1

Ancient stories often are the result of cultural memories of real events. But there are additional facts you should take into account before you hypothesize the rather unlikely cause of a nuclear weapon produced by an advanced civilization that has left no other evidence of its existence in the archaeological record.

A meteor large enough to cause an event with the destructive power of a nuclear weapon hits the earth about once per century.

Radioactivity is not distributed evenly around the world, there are some areas that have high background radiation levels. Up to 400 times normal levels have been observed. The highest are found primarily in Brazil, India and China. The higher radiation levels are due to high concentrations of radioactive minerals in soil.

Answer 2

The only proof here is proof of an excellent imagination and an interesting coincidence. Similar to the "proof" of man made global warming

Answer 3

Radioactivity would've left its signature mark on the land....., as well as glass around the blast site. that to me is the evidence of a nuclear explosion.

Answer 4

Or a severe meteorite impact.
