No reason why there couldn't be. Just don't expect it to look like humans.

There is almost certain liquid water on Mars and Europa. IMHO, that means there is almost certainly some kind of microbial life. And, we know from experiments conducted by ESA, that lichens could live on Mars. If you're talking about sentient life, the question is more complex.
So far we've seen no verifiable evidence of other sentient species. That said, I believe with some certainty that somewhere in our galaxy at some past, present, or future time, a sentient species did/does/will exist.
Why haven't we heard from them?
Perhaps they are not technologically advanced enough to be heard. They may be mastering stone knives right now, or experiencing their own Rennaisance.
Perhaps they are here right now. Any species sufficiently advanced to travel interstellar distances would be able to hide or masquerade with ease. That Boeing 737 that just flew by may be a surveillance craft.
Perhaps they are so far away they will never notice us and vice versa.
Perhaps they existed a million years ago and died out.
Perhaps they will exist a million years from now.
It is really impossible to know for sure.
The Drake Equation suggests that there is sentient life out there. The Fermi Paradox casts doubt. Play around with the calculation form at the second link and see what you think.

When Frank Drake developed his equation, the estimates at the time gave an answer of 10 civilizations in our galaxy. Other estimates gave answers up to 5,000. The current estimates give an answer of 0.0000008.
these are all estimates, so the true answer is unknown...
The Hitchhiker's Guide to the Galaxy states that the population of the universe is zero.
"It is known that there are an infinite number of worlds, simply because there is an infinite amount of space for them. However, not every one of them is inhabited. Therefore, there must be a finite number of inhabited worlds. Any finite number divided by infinity is as near to nothing as makes no odds, so the average population of all the planets in the Universe can be said to be zero. From this it follows that the population of the whole Universe is also zero, and that any people you may meet from time to time are merely the products of a deranged imagination."

Yes,
There is much life we don't understand on our own planet, bacteria and prozozoas that live without oxygen, life forms that live on the bottom of the ocean without sunlight...we are just discovering thta life is much more powerful than we estimate...as for other planets we are just finding them in the last fifteen years that there are other planets which makes sense and in the known universe there are billions of galaxies with trillions upon trillions of stars with kazillions of planets...what do you think are the odds that there is other life out there...pretty good, I think that it is arrogant to even suggest that we are the only creation in the universe God has created, who knows the depths of God?

Sure, why not? I beleive in God and the Bible. God is capable of anything... why not life on other planets? The Bible is the word for how we should live our lives on earth. It does not encompass everything about what God has done. It only permits us to understand how to live the best life we can on earth and how to receive our eternal life / salvation through Christ. We do not need to know if there are beings on other planets to receive our gift of salvation. Remeber, a gift is not really received by someone until they open the present. Jesus says "I stand at the door and Knock" and He gives those who truly accept Him and His gift a guarantee to life eternal in heaven with Him.

Of course. In all the universe, do you really believe we're the only one with life? Don't expect it to have evolved elsewhere as it did here, but there is definitely life out there.

There's life in the Andromeda Galaxy.

Could there be only one green grain of sand in the world?

I have to ask is it possible for no life anywhere but Earth?
