Almost assuredly yes.
The most important requirement for life is liquid water. Too close to a star, the water evaporates. Too far away, you get ice. People used to think Earth was the only place in the solar system that could support life.
We now know Mars once had liquid water. If it had liquid water and life did arise, it's possible Martian life may thrive under the surface (believe it or not, microbial life on Earth extends down several miles under the Earth - in fact, the weight of all life under the surface of the Earth is greater than the weight of life on the surface. That's a lot of microbes).
Not only Mars, we also know that through gravitational tides, at least 2 moons around Jupiter and 1 around Saturn may have huge liquid oceans. Heat is generated as the moons are stretched and compressed by the enormous gravitational tugs of the host planets. There could be more liquid water on each of the moons than there is on Earth (each moon would have oceans that are miles deep). Sure the surface is frozen and inhospitable, but the interior could be warm and comfortable, just perfect for life. We should know in about 20 years.
Finally, it now appears that planets around distant stars are commonplace. Already astronomers have found dozens of "Hot Jupiters", planets the size (or bigger) than Jupiter but in orbits far tighter than Mercury's around our sun. These Hot Jupiters are now thought to be a perfect catalyst for the formation of Earth-like worlds. Not only that, regular Jupiters can certainly help form Earth-like worlds (it did here).
The fact is that there may be billions of worlds with surfaces of liquid water, and billions more with warm oceans under a frozen surface. Billions and billions of chances for life to arise, and that's only our one galaxy. There are hundreds of billions of galaxies out there in the universe...
Stay tuned. In your lifetime, you will have some answers.

God put humans on this earth for one purpose. His original purpose was evident when He told Adam and Eve to "be fruitful and become many and fill the earth and subdue it, and have in subjection the fish of the sea and the flying creatures of the heavens and every living creature that is moving upon the earth" Genesis 1:28 His purpose was for people to live on earth forever, PERFECT people. But of course, Eve and Adam sinned, caused the downfall of man. This altered God's original purpose for humankind.

Yes, and we are already here. Over the centuries, your planet was a curious place to visit once or twice and was not considered very interesting . Sure, your wars showed us how undeveloped you are as a species and your infantile,(in cosmic terms) dependence on god concepts does not bode well for you. We are now showing an interest in you because it is not often that we get to observe a species commit suicide. You are so close to maturing as a sentient species and it will be a shame to see you kill yourselves. There are just not enough of you becoming rational enough to force the issue. You let the least among you determine your fate, so be it.

The Milky Way is believed to contain over 100 billion stars. The Milky Way is just one of millions of known galaxies in the universe. These galaxies also contain stars. Stars just like our sun. And it's already know that there are planets orbiting around them. Just based on the laws of averages that should tell you that there is life out there.

Life as you'd expect (like ourselves) hasn't been found yet but microbes and other organisms have been found.
With that said, though there's no proof of intelligent life in the universe, the chances that there isn't life other than ours is pretty slim, with the size of the universe. There has to be life out there besides us.

Yes. In fact Aliens have abducted Steve Guttenberg and used him for breeding a super race called the Guttens to destroy mankind. And did you know that hedgehogs come from a planet called Gohegdeh?

Miliways.
Milliways - the Restaurant at the end of the universe.
Go there on a good night when there are customers from all of the 87,573,100 populated planets and ask the question. They are looking for a good comedy cabaret act.

Um, that's a question that scientists have been trying to answer essentially since we discovered there was a universe. Yep...still not answered.

No one knows. However, with the billions of stars that have planets orbiting them, there very probably is life.

Except heaven and the earth no other place life exists.
