Pictures of our solar system never gets old to me. I'm always amazed by the beauty of other planets and moons that used to be out of reach. But sometimes, something more profound appears. Once in a while, similarities with home are discovered.
Here is one, for example: After Europa -- one of Jupiter's moons discovered by Galileo Galilei -- NASA is almost certain that there is water under the surface of Titan.
The discovery was made after observing tides around 30 feet high on the surface of the moon, suggesting that Titan isn't entirely made of solid rock, but instead the surface would lie on a sub-ocean.
You might argue that there will be no light from the sun, therefore life cannot emerge, but studies on earth showed that water and heat is all life needs. And for the heat, it would come from the strong gravity from Saturn, intensely squeezing the planet during its 16-day orbit. Do you believe in life on the Saturn Moon?

Data from NASA's Cassini spacecraft have revealed Saturn's moon Titan likely harbors a layer of liquid water under its ice shell.

We'll either meet extra terrestrial organisms, a pre-space faring race on another world, or satellite probes form another world, cause it's unlikely we'll meet a space faring race.
However, I think that they are not like us, physically or psychologically (maybe they're smarter or not as smart or equally smart even). I think their location in the universe, the gases in their atmosphere, etc., will have given them different physical forms and functions. :)
- The universe is a huge place. So huge, in fact, that even when a photon of light travels at over 676,000 mph in a vacuum, that photon takes more than 13 billion years to cross it. On top of that, solar systems are plentiful in the universe, and so are asteroids like the ones that brought the materials of life right to Earth, and galaxies chock-full of these solar systems and asteroids. Even with so many galaxies, solar systems, and asteroids acting as the universal UPS system, how in the universe could Earth be the only planet capable of supporting life on it?
- Just because we haven't received signals yet from aliens doesn't mean they aren't there. They might have technology too advanced for us to pick up their signals, or they might not have the technology to send signals out very far. They could be uninterested in talking with us, for some reason. They might be so far away that their signals haven't reached us yet. With so much background radiation coming in from stars and man-made satellites, their messages could easily get lost and never make it to us. And the signals are certainly going to be in a different language than any of the ones we humans have. (Try listening to a conversation in Arabic in the middle of a stadium full of screaming fans, if you do...

- Life doesn't come in one form - it adapts to the environment in which it develops. That's why there are sea creatures in cold caves filled with darkness and on the ocean floor near boiling-hot steam vents. The same applies for other worlds - we've found worlds like Titan where the oceans and rivers are made of methane instead of water, worlds shrouded in a permanent haze, and worlds that don't have strong magnetic fields to protect their atmospheres from the star's harmful rays completely. Evolution will find a way to spread life all over these worlds, regardless of whether those life forms resemble anything we can find on Earth. Therefore, if you really want to find aliens on another planet, you have to learn more about the planet itself to find out what the aliens will look and behave like.
TL,DR: The universe is just too large for Earth to be the only place where life exists, and just because they haven't contacted us yet doesn't mean they aren't there.
For everyone (the rest of everyone else ha), they would simply hear about our expeditions and most probably assume that we are doing something we shouldnt be doing, hence when super massive evil aliens show up to destroy Everything and Everyone, it is our fault.
Would be fun, but for some reason the opinion of the Public mass will never see it that way.
and at another point looked like this
can have life and if we are just one planet around one star in an "ocean" of stars,
then i have no problem knowing we are not alone.
Maybe even beings we think to be fictional reside somewhere in this crazy universe of ours--or, perhaps, in one of the parallel universes we are surrounded by.
