Why do we not find the skeletons of demons slayed by Krishna or Rama though most of them existed in dwapar yuga only, as we can find remains of dinosaurs easily then why not of demons?
Answer :
There can’t be any remains by cremation.
Dinosaurs were not cremated. The idea of tracking back history through archaeology is speculative.
Fossils remains when there is a natural death and the body is buried by natural causes.
The Vedic culture was all over the world, and the default manner was to burn the body. So tracking human life is difficult.
