Not yet, but we are getting VERY close. At least in our Solar System, the Mars rovers are making excellent progress in discovering past or present life. There is also a mission that is planned to send to ‘Europa’, a moon of Jupiter to see if there is any life under it’s surface.
And Scientists like me are studying extrasolar planets, to find out if there is any kind of life outside our Solar System. Just wait for 10 years, you will know the answer: “Are we alone in the Universe” ?
