There is almost certainly life elsewhere than Earth. I'd say a 99.999999% chance. In fact, it may be within our own solar system. Jupiter's moon Europa has warm, liquid water beneath its outer ice layer. Besides, there could be life that has evolved to non-Earth-like conditions.
That is 2 places in our own solar system that could have Earth-like life. Scientists have discovered over 500 solar systems in our own Milky Way Galaxy with more being discovered all the time.
Hubble has discovered over 100 billion galaxies, and that is only what we can see so far.
We are not alone, we are not special. That is all.
Edit: Saying we are alone because we haven't discovered life yet is as egotistical as saying Earth is the center of the universe.

2 RepliesThe conditions required for carbon based life forms to exist are very small, too many variables. The probability of it existing elsewhere in the universe, (taking into consideration how much matter there will ever be in the universe) is nexto 0. But there is hope! Life doesnt always need Earthly like conditions to survive AND the fact it ever happend on Earth goes against all probability.
