Study: If aliens exist, they probably want to destroy us

When considering the prospect of alien life, humankind should prepare for the worst, according to a new study: Either we're alone, or any aliens out there are acquisitive and resource-hungry, just like us.

These two unpalatable options are pretty much the only possibilities, according to the new study. That's because evolution is predictable, and alien biospheres should thus produce intelligent creatures much like us, with technological prowess and an ever-increasing need for resources.

But the fact that we haven't run across E.T. yet argues strongly for the latter possibility — that we are alone in the universe's howling void, the study suggests.

"At present, as many have observed, it is very quiet out there," study author Simon Conway Morris, of the University of Cambridge, told SPACE.com in an e-mail interview. "And given many planetary systems are billions of years older than ours, I'd expect us to be best grilled on toast back in the Cambrian."

I think we are alone due to that last paragraph.  If most of the other systems are billions of years older than ours,  I think they would have tried to seek us out by now.   They certainly should have the technology.  I hope there never was life any where else to begin with.  The prospects of our survival diminish if other life forms died out.
