(Man will become extinct like every other species has in the past.)
We will become extinct! If we do not find other places /planets to live on. Earth is a ticking time bomb on the evolutionary calender. Whether it be a celestial collision, a major volcanic eruption or the human element??? One of those scenarios is going to do us in. Religion might save you....but it won't save the planet. Something to think about, as some of the smartest men on earth are now exploring the Red Planet. Go NASA!
