Hi. I work at NASA's Johnson Space Center, in Houston, Texas.
That part out of the way, I suggest you look into the composition of comets. I also suggest you look at the moon (though there is little there to find). You might try Mars, which has polar ice caps, the same as Earth. Moving further out, there are a few items called the outer planets, such as Jupiter and Saturn, etc. that are composed partially of water. I will grant you the fact that the water involved in these cases is mostly ice, and is therefore note "water" in liquid form.
In orbit about these planets, you will find moons. I ask that you look to Jupiter's moon Europa and Saturn's moon Titan. Not only are they composed of vast quantities of water ice, there is also very strong evidence that beneath their frozen surfaces, there may be vast oceans of liquid water.
So, being that there is most likely some liquid water on these bodies, and they are not part of Earth, I suspect there is a very good chance that life exists somewhere besides Earth.
Now, as they are very far from Earth, and have never been taught the good word of the bible and jesus, I strongly suggest you and your fellows get together and start a missionary trip to bring salvation.
It will make it a lot more pleasant here on Earth, too.
