Due to human causes or natural causes? end of the world meaning basically most life on earth being ended by...something. war? nukes? some natural cause? one or the other is going to happen. when? its the ugly truth...if somehow its not through nukes or war or some other testosterone shit then it'll be another natural cycle of the earth...we got a ways to go yet. dinosaurs lived for 165 million years, the earth's most successful species. we've been around 4 million...so what natural disaster will cause our demise? how does god play into all of this? if religion is so legitimate, why are there no traces of it anywhere in any species before humans?
