Greatest Achievement EVER?

On the 40th anniversary of the moon landing, a lot of folks are calling that "giant leap for mankind" our greatest achievement.  There's no doubt it was incredible - especially at a time before cell phones and computers and GPS were even available to us.

But was it humanity's greatest achievement EVER?  Was it bigger than the invention of the Internet, the discovery of the New World or the Wright Brothers' first flight?  Can you think of any achievements that rival our first steps on the moon?
