I honestly think we are 10 years from confirmation of life on Mars.... but suspect it will be transplanted Earth life (panspemia)... or that Earth is transplanted Mars life. A second genesis I believe awaits our discovery on Europa and Enceladus, 20 years away.
CONTACT (with another intelligent species) I hope I see in my lifetime.... I say 50/50 in the next 40 years, and I'm hoping I'm good for 40 more...

Over 200 planets in other solar systems have been found so far in our Milky Way Galaxy alone. All of these planets are within 500 light years of us. Our galaxy is about 100-thousand light years in diameter, so those 200 planets are right in our own backyard. How many more planets there must be much farther away in this galaxy of ours that contains about 200-billion stars.
There are at *least* 200-billion other galaxies in the universe, most of them with more or less 200-billion stars each.
Earth circles just one ordinary star among about 70-sextillion others (...http://www.abc.net.au/science/news/space/SpaceRepublish_910295.htm...) The odds of it being the only one with intelligent life are astronomical....pun intended : )

Because we are just one single planet with life here in our solar system.. but there is most definitely other beings out there. our uinverse is way to large to even think we are the only

There are so many billions of stars and galaxies, statistics say there has to be more life out there.

because the universe is so big , that chances of not existing life on another planet is practical zero.
