In fact we have no more time!
Just think, as archaeologist Robert J. Braidwood wrote before, if we see all history as a one day, it is now one to midnight. Human groups living in Africa made first stone tools only one minute ago. Jesus was born just 1 second ago. Roman empire, Middle Ages all were in one second time.
Before that one minute, it was the evolution of mamalians, reptiles, other livin creatures. Before 3-4 hours ago, there was no life on earth.
So, we should understand that, we just see a small part of our earth's adventure. We think 70-80 years is a lot of time. Yes it is, but only for us. It's nothing for the earth, which is nearly 4-5 bilion years old. It's nothing if we compare human evolution. First humans apeared 2.5 milion years ago.
Dinosours lived the timespan between 180-65 milion years. That were their time. But the earth changed, and they disappeared.
Human will disappear too. The earth is changing faster. We change it. And it's not a success. We kill other living creatures. And everyday one specie disappears because of our pressure on the nature.
After, 10-20 milion years, maybe a understanding creature will see our remains as a greyish ash layer in a geological statigraphy (as we see Miocene like this today). Maybe they will find atomic bomb explosions too. But we will disappear. But the life in earth will continue. I believe.
