there will come a time when all of us are dead. all of us. there will come a time when there are no human beings remaining to remember that anyone ever existed or that our species ever did anything. there will be no one left to remember aristole or cleopatra let alone you. everything that we did and build andwrote and thought and discovered will be forgotten and all of this, will have benn for naught maybe this time is coming soon and maybe it is millions of years away, but even if we survive the collapse of our sun, we will not survive forever. There was time before organisms experienced consciousness, and there will be a time after. And if the inevitability of human oblivion worries you, then i encourage you to ignore it. God knows thats what everyone else does. 
oh god no the fault in our stars
Dat grammer and dem typos doe…
Ah, the irony.
Well that is a good way to think about it I guess everything is for naught and we should sit around and get fat because apparently humanity is trapped to earth. This solar system totally not going to travel to other planets or anything. Lets not do anything so history can be forgotten. Lets not use our borrowed time as a motivator to make humanity reach for the stars.
Just my thought on this depressing stuff.
