It is more likely than not that there are many planets in the universe with life and many of those may have "intelligent" life.
We have just only obtained the ability to detect planets in other solar systems and we can only detect very large ones. We do not have the ability to detect Earth like planets.
Within our own solar system, we have yet to find undisputable evidence of life on any of the planets we have activley searched for it. Many scientists are optimistic about finding microbial life forms within our solar system though. There are still pleanty of places on Mars, for example, that we simply haven't looked, and there are many moons in our solar system with the potential for supporting microbial, and even more complex life forms. Jupiter's moon Europa is a good candidate because it is covered by a sheet of ice and thought to have liquid water oceans underneath. Due to Jupiter's gravity constantly tugging on the planet, it is likely geologically active and thermal vents may exist in it's under ice oceans. Here on Earth, underwater thermal vents are teeming with life, even though no sun light reaches them.

anybody who claims to be able to respond to this question with a sure or no is fooling themselves. we haven't any foundation on which to assert what the opportunities of an earthlike planet assisting existence are. we do not even recognize how this befell on our personal planet. It appears like existence purely sprang up once in the international as all existence the following makes use of extra or a lot less an similar genetic code. If the opportunities were 100% then does not or not that is likely to take position more effective than once on one of those enormous planet? most of the different factors contained in the Drake equation in addition won't be able to be more effective than guessed at.

It's not possible to prove or disprove this for a fact. But given the "ordinariness" of our planet, the abundance of different life forms on our little rock, and the vastness of the universe, it would be almost silly to believe we were the only planet with living beings on it!

No, the galaxy has many planets that support life. We have visited many of them and are now here on your planet. 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. Your infantile,(in cosmic terms) dependence on god concepts does not bode well for you and neither does your penchant to breed beyond your planet's ability to sustain 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 truth is, no one really knows. I believe that there are other planets out there with living beings. How many of these beings are intelligent life, we do not know. We can never know for sure. Beings whose technology is superior to ours will never make contact with us because that would disrupt our development as a species. Those beings with the same level of technology as ours cannot make contact with us. Those beings whose technology is lesser developed than ours cannot make contact with us. These are just the beings who are intelligent life forms. Planets with no intelligent life we may never even know exist.

With the size of the universe, it would be arrogant to claim there is no life outside of Earth.
That said, and despite all the efforts to sterilize the spacecraft that were sent on Mars, I am pretty sure some bacteria hitched a ride on the probes sent there. Are those bacteria still alive there? If they are, then, there is life on Mars, but it came from here.

WE DON'T KNOW
As of now, it is the only planet we KNOW that has living beings. There may be others out there. We don't know.
