You're mistaken, Gigolo. To date, we have not.
What we discovered was a rock that shows what some scientists consider evidence of fossilized organic life on Mars, and what others consider to be a Rock from god-knows where that's been contaminated by being on Earth for so long with no definitive fossilized evidence of anything anyway.
There's a good number of peeps that feel we could discover something on Mars (as it does appear that rivers of water once flowed on the planet - and have several probes both already there and on the way to look for signs of life), and hope to discover something on Jupier's moon, Europa (it's generally believed there's an ocean of water under the moon's icy surface - we have a mission in the works aiming to drill into that sea and scoop up a sample right now).
Insofar that we know, a requirement of life is liquid water... and there's plenty of water spread throughout our solar system (though most of it's not in liquid form at present)... so we keep looking as our society's budget for Big Science allows us.
Personally, I'm sure we'll find it soon enough... everything I've studied and know leads me to feel that "life" is the rule, and not the exception... but, we still haven't found life outside our own planet yet.
