maybe if we are able to survive some thousand more years we could reach the light in our minds.

Yes, maybe. But the way we are approaching our demise, I really suspect humanity will last another 200 years, thousand years is too ambitious. Mother nature has been always favourable to us, how long she can withstand the way we torture her you think? We are already witnessing global disasters, unknown pandemics, if this continues which I think will do, I better call myself the luckiest if I manage to leave the world in peace.
