Life has not yet been discovered by us humans, we haven't even discovered half the life here on earth. Earth is less than microscopic compared to the rest of what is out there, so the question is, is it possible for this to be the only planet out of an infinite array to hold life? No. There is definitely something out there, there is definitely life in many, many places that we don't know about. It makes sense to think that the earth like planets we have discovered trillion miles away from earth are looking right back at us, wondering the same thing as us...

Yes, the planet Earth is part of the solar system, so all the life on Earth is in the solar system. Yes, our Earth is part of the Solar System. As to life on other planets - both within our Solar System and in other solar systems (planets around other stars), nothing has been proven yet, one way or the other. Specifically, no life has been found on other planets. It would seem probable, though, that what happened on Earth can happen again - perhaps on nearly any planet, perhaps only occasionally.
It has dogs, fish, trees, people, and cars on it.
Archaebacteria are the oldest and most primitive forms of life on planet Earth. It is postulated that primitive life on other planets would be most likely to resemble Archaebacteria. In addition, Archaebacteria were the first life forms to exist on Earth, so studying them allows xenobiologists to postulate how life may come into being on other planets.
Yes; there are three. One is ceres(a dwarf planet) which is between Jupiter, and Mars. Eris is the second dwarf planet located past pluto. There is another planet that scientists researched on.
mars
We don't know about any other other place, besides Earth, that harbors life. But many scientists think that there is life on other planets.

Scientists say that life can be expected to have evolved on other planets, wherever the environment is not so hostile that life can not be supported. They say that in this vast universe there must be many such planets that can support life and that some are likely to support intelligent life forms even more advanced than humans. Whether we believe that our God created the life on other planets is a matter of human faith. No doubt any intelligent life on other planets will never have heard of Earth's gods.
YES! it isbecause if their is life on another planet, if anything goes wrong we can go to that planet.
Earth's scientist have not found life on other planets to date.
All planets in the solar system, besides earth, are airless. These planets are not able to contain human life.
Yes. Probably not in this solar system. But there is a good chance that among the millions and trillions of possibilities, there are other planets that have developed life.
Yes, only on the Earth. We don't know if the other planets have life
Astronomers have found Earth-sized planets in other solar systems.
There is life on other planets. Imagine, there are 1000 planets in the Universe for every grain of sand on the earth. That's how many planets there are, so scientifically, the chance that there must be life on other planets as well is much greater than the chance that there is no life.
