It doesn't have to exist, but there is a strong probability that it does exist somewhere along the magnitude of 500,000 worlds as advance as we are technologically and another 50,000 or so that are far more advanced than what we are.
Start with the calculation that there are 50 billion galaxies and lets say for the sake of argument each of those galaxies have approximately 100 billion stars, that means there are approximately 5 x 10 to the 21st power stars out there. Using a rule of 1% to get to what our solar system is like that is how I get to the 500k and 50 k numbers from before.

Strictly speaking, it doesn't have to. However, the possibility that ET life exists can't be considered to be zero, due to the enormous amount of stars, literally billions of billions. It is possible that life exists somewhere so far away from us, that even making contact would take thousands or millions of years. Personally, I wouldn't lose any sleep over it, whether or not there is ET life somewhere out there.

With the infinite amount planets in space, even the smallest probability of life would yield a substantial number of planets with life on it.
The two real questions are: the first is did they exist and die out, do they exist now, or will they exist when we die out?
The second is: if they exist are they less advanced, as advanced or more advanced then we are. If they are more advanced than we are, are they advanced enough to visit us or at least communicate with us.
Cheers and Good Luck!

Most scientists agree that the probability of there being life elsewhere in the galaxy is very high.
Whether or not there is other intelligent life is debatable, but in my opinion it is foolish to think that there is not, now that we know just how vast the universe is.

I believe this question to be of a rhetorical nature because it mostly depends on your beliefs: whether you believe in creation or evolution. One may say no, because God created "the heavens and the Earth" in the beginning. People who believe in elvolution or what not, may say yes, because if life on our planet is possible, then what about life on others? Some may think that other life forms are drastically different from us or the same.
This is something we know nothing about, and will most likely never know the truth about.

ET life doesn't have to exist, but lets just say it's extremely easy for it too exist.

The odds are in favor of there being other life forms somewhere in the galaxy. But the odds of them having visited us are pretty minute.

Infinity is a large place. I think it would be kind of arrogant for us to believe that life of some sort could never have generated somewhere or sometime else in infinity.

Most deffinately!
The rest of the universe (in general!) is not drasticaly diffirent from here, so what happened here is bound to have happened billions of other places as well!

The odds are that there is life outside of the earth.
