Are we alone in universe?

While accepting extraterrestrial life probably exists, astrophysicist Neil deGrasse Tyson rejects the assumption aliens would be a malevolent force.

“No one knows how an alien will behave,” Tyson told CNN. “Any suspicion that they will be evil is more a reflection of our fear about how we would treat an alien species if we found them, than any actual knowledge about how an alien would treat us.”

Either way, contact with extraterrestrials would be one of the most profound moments in human history, with deep spiritual implications. If a meeting ever occurs, one can’t help feel jealous of the generation that lives through it. But then again, if we believe Hawking, maybe we should count ourselves lucky not to.
