Indeed, imagining the world without us is almost an impossible task or maybe I should say imagining us in another world, another realm. I find it very strange that even religious people are sometimes desperate to prolong this life as much as possible. Sure, the afterlife, Paradise are all very nice, but nobody is in a hurry to go there...
Thank you so much for the book recommendations, you have just saved me from a boring book I was reading. I just checked my Kindle and I have two Borges short stories on it... hopefully they include the one you mentioned, too!
