The common wisdom is that we are curious about whether we're alone in the universe. That, if you ask me, is why we do lots of stuff. And it's not just a guy thing.

Some heave water balloons off skyscrapers. Some get pregnant just to show they can, while others drive cars at 115 mph and still others trade stocks online.
