If there were life on other planets, wouldn't they most likely be single cell organisms able to survive in extreme temperatures?

Yes, I think a lot of them would have life like that. Some would have more advanced life as well. The discovery of even one cell from another planet is a huge deal. I would love to get my hands on the DNA and sequence it.

There are more planets with extreme conditions that planets with conditions like the one we have here on Earth. Also, life appeared on Earth about 3.5 billion years ago, and the first multi-cellular organisms appeared only one billion years ago, so for most of the time life existed on this planet, it was only in the form of single cell organisms able to survive extreme conditions. Probabilities are thus that most life on other planets are indeed very primitive single cell organisms. Which does not rule out the possibility that some would be in an a more advanced form, perhaps even having reached the stage of technologically advanced society. We won't know until we get there (and that could be a while).

On the planets in our solar system -- quite possibly.
However, keep in mind that we're finding planets around all kinds of other stars in our galaxy now...the current methods we use to find them really only let us find Jupiter-type planets (large gas giants who have a large gravitational effect on their stars), but since we find so many it's very likely that there are lots of solar systems like ours, that also have 1 or maybe 2 planets in the "habitable zone" where liquid water can exist, and were temperatures are moderate. These could very well have complex life as on earth. We just haven't found it yet because our methods aren't quite good enough.

The funny thing about Life is that it is a constant element is any galaxy. To respond your questions, yes there are plants in our own solar system and even the galaxy we live in that have a single cell life forms. However, Life has a way of being the great adapter to any environmental condition no matter where it is located. Life soul purpose is to evolve and became something greater. Earth is just one community in this galaxy of trillions.

It depends where they are along the evolutionary road. A hospitable planet could just as easily be in the comfort zone which is environmentally friendly to life.

oh for sure... Nothing more complicated likely exists in our solar system. Outside of our solar system anything is possible though. There are millions and millions of hospitable planets (mathematically) in our galaxy alone and I am positive that complex life exists on exo-solar planets.

Any answer out there is speculative. Some will be backed by very good scientific theory, but its still a theory. So why don't you work towards the answer on your own. Its going to take a lot of research. Good luck

If you mean in our solar system,you are probably right.
If you mean all possible planets in the universe this would certainly not be the case.

no, however, in the milky way galaxy, it is so. the other planets already have been discovered as lifeless, atleast on the visual level. but in other galaxies, it is potentially possible that there are other life forms in other galaxies not yet explored.

I think there's life on other planets, but intelligent life is few and far between.
