Tho I may not be alive to see it in the next 25 to 100 years I think were going to find out life is so abundant in the galaxy people will look back at 2015 and see people who thought the earth was flat. We are getting so good at finding planets and spectrometry. In just one year while analyzing just one tiny patch of sky the Kepler observatory has found over 700 planets orbiting stars. Now its believed EVERY star has at least one planet. Most have far more along with many moons.
In the next few years observatories will be launched that make Kepler and Hubble look like toys. They will be able to analyze the light reflecting off these planets and tell us what they are composed of. In other words if a rocky planet is in the "Goldilocks" zone of a stable star and we are able to analyze the light reflecting from liquid water, oxygen, Chlorophyll , carbon dioxide...ect we can pretty much surmise the planet holds life.
And there are 100 m to 200 m Galaxies in the known universe and at least 100 m stars in each galaxy. My belief is the universe is teeming with life beyond count and even in the Milky Way there is intelligent life numbering in the millions.
The arrogance eh? What makes us so special?
