I dont think we will be here for.much more time,in 100 years we can be in other planet or something,but as know the human evolves like all the other creatures,we all are animals,we was homo-sapiens and evolved,will dont be humans in the future,but.our next evolution,how far it goes?
well we can survive SINCE they take what is needed to survive in other world,i have heard in a news that big part of all iron and gold will disappear,and this is bad to the technology,it does not need only iron and those cables,they use a bit of the gold too,but as i know there arent much gold as before,this us an trouble to technology that they must find a way to solve before "invade the galaxy"
I dont guess humanity will go much far,much wars,holocausts,death of the flora,new virus etc
in at leaat 40-60 years i guess there will be another holocaust,then,after his end,will probqbly start new techology times,new cars,planes etc
