For how long is human life known to exist in Nepal?

Records show that human life has been in the region for at least 9,000 years

Its first known visitors were the Kirant people who settled there

I think more prudent question for now would be : FOR HOW LONG YOU THINK THE HUMAN LIFE WILL CONTINUE TO EXIST IN NEPAL?
Some observations:
1. We are killing each other for apparently no good reason, PLOITICS!!
2. Our mind is set on past and not in the future, it seems we are trying to bring back the past and ignore the future.
3. We severly damaging our own environment, culture, identity and happiness, again justifying on the basis of the past and not thinking of the future.
