Actually the Hindu Vedas describe what appears to be atomic wars that occurred before the last “Earth Cycle”. An Earth Cycle is the time it takes the Earth’s poles to precess 360 degrees, about 28,000 years. Interesting stuff.
It’s much more likely that accounts of that kind describe impacts from space, however:

No. The exact translation refers to Time, not Death.
BG 11.32: The Supreme Lord said: I am mighty Time, the source of destruction that comes forth to annihilate the worlds. Even without your participation, the warriors arrayed in the opposing army shall cease to exist.
There are other passages you could fit that nuclear interpretation to but it would be heavy confirmation bias and wrong, IMHO. [/snip]

Precession takes about 26,000 years to complete, assuming that it does complete, and is primoridial.
