Look towards the Stars.

It's really surprising to think about how much astronomy has changed throughout history. It was four hundred years ago when Galileo first pointed his telescope towards Jupiter making the discovery that other bodies in space do not only orbit the earth. It wasn't until 1922 that Edwin Hubble discovered that the universe extended outside of just our own galaxy. Now, using the most advanced astronomical equipment in the world we have been able to find nearly earth like planets orbiting other stars. So far using the Kepler space telescope, astronomers have found over 700 of these exoplanets. Recent statistical analysis has shown that there are even more rocky earth-like planets than there are gas giants like Jupiter or Saturn. This is why I believe that within the next 100 years, man will find life on other planets. This idea excites me because the repercussions of finding extraterrestrial life would be immense.
