Ofcourse. We can't be possibly the only race in this universe! We haven't even explored 0.01% of the universe so we're just like a grail of soil in a desert. But I call the UFOs in the news BS. I think its just for some attention you know.
Well we can't even understand most of the universe right now. All the stars, planets and galaxies that we can see today make up 4% of the universe. The rest is stuff that astronomers can't detect, see or even comprehend (usually dark energy and dark matter). If we consider physical exploration only, then we can surely say that we've explored nothing in the universe. A single moon in comparison to all the objects in the universe would equal to a shameful percentage.So far Voyager 1 is the most distant probe that humanity has. As of September 2012 it is 18.2 billion kilometers away from the sun (that's the information that I found).
In other words our most distant probe has traveled 0.0001923741 light years. To represent a more clearer picture:
1 light year is equal to ~ 9.4 trillion killometers (i.e. 9 460 730 472 580) ; It is estimated that the diameter of the observable universe is about 28 gigaparsecs i.e. 93 billion light-years big.
First multiply 93 billion by 9.3 trillion kilometers to realize how big this is. How could a rational mind say that there is no intelligent life in it besides humans?
