With all due respect, jeeprube, you gotta let go of all that eschatological stuff.
The "end," as presented in the Bible is a fantasy.
The earth is going to keep rolling along for 100s of millions years in the future just like it already has for hundreds of millions years.
Species have come and gone and will continue to do so--and as painful as it is to contemplate, that includes humans.
The human species is just a blip on the geologic radar screen. So far we haven't demonstrated any unusual characteristics or abilities that indicate we are going to be long term evolutionary survivors. We could be taken out in a blink, just like the dinosaurs.
That being said, this is a wonderful world with so much incredible life and diversity. Enjoy it to the fullest while you're here.
