Can there be life some where else but we don't know that?
I mean that if there is life in a galaxie or in outer space.

I am sure there is. There are so many galaxies out there and the sky has no beginning or end..I am sure there is more life and planets out there but we cannot see it because we are still to far away from them.

This is a very complex question that a lot of people would like to know the answer to! There are literally billions of stars in the Universe and therefore it is likely by the law of averages that there is a planet about the same size and the same distance from it's similar powered Sun (star) and having a similar chemical composition. If we assume these are the only factors that are involved to make it possible for life then it is probable that life exists somewhere else in the Universe. Life on a planet also has to start somehow. It has been found recently that the building blocks for life are found in meteors that have reached the earth from space, so it is a good possibility that life may have started this way. Also, we have found life on this planet in the most unexpected places, for example, under the sea around what are called 'black smokers'. These are extremely hot and never see the light of the Sun and therefore do not use this as a energy source. This proved to scientist that life does not always follow the same rules. So, possibly, there may be life formed in different ways on other planets. This could be very simple bacteria or something far exceeding humans in evolution. The question will we ever talk to this other life is another thing altogether!

If you have 100,000 Billion stars in the Milky Way Galaxy alone, and each one is more or less like our Sun, then you could have a possible 100,000 Billion other solar systems out there. Each of those solar systems might have from 0 to 10 (or more ) planets orbiting around its sun. And, one of them might have just the right stuff to be the equivalent of our Earth.
Negative points:
The nearest star (other than our Sun) is some 4.4 Light Years away from us.
Almost all of the stars you see with the naked eye on a clear night are within the Milky Way Galaxy (our's).
The Milky Way Galaxy has a diameter of about 100,000 light years and is shaped like a flat, spining disk that is not real thick, maybe a few thousand light years thick. Spiraling arms extend outward from a dense cluster of stars at the very center of the Galaxy. Our Solar System is located about 1/3 of the way out from the center on one of those spiral arms.
So...your sought after Earth equivalent planet might be as much as 70,000 light years away, and by the time it is discovered, it may already be a dead planet (but we won't know about it's death for 70,000 years).

Nobody knows. But if you look at the size of the universe (as we know it now), just by computing the odds it would be extremely unlikely that we are the only place in the universe with life.
If you believe in the panspermia theory, life on earth originated in outer space and arrived on a meteorite.
And, of course, if you believe in the good book, we probably are alone. Even so, references to giants and children of God may indicate other kinds of intelligence there too.

There is a great probability there is life elsewhere in the universe. The intersting thought is whether there is other intelligent life.
Just try to wrap your mind around the thought that there are other life-forms out there with human-intelligence and they are wondering the same thing we are: if there is life outside their realm. But we live so far apart it is irrelevant to even try to comprehend it.

The odds are overwhelmingly in favor of life to exist elsewhere, and for other planets like Earth to exist.
How far away is the nearest one? That is what we do not know.

I'm Sure theirs life on some other planet out there.

Probably not in this galaxy because we have explored it but we'll never actually know if there is life in another galaxy because we don't have the technology to go there.
