We dont know but I think there is because they might be humans in different forms and shape living in another galaxy, they might some soul doing the exat same thing they are doing or they might be that the top of the food chain will be tigers, not humans and tigers go to work, school etc and humans be in cages also they might look so different andthey might think we are so ugly, dangerous and we might think there ugly. They might think humans arE aleins and they might have 6 eyes that are shaped like a cube, we think thats stupid and they think that " This gus go 2 eyes shaped like a oval thats nasty" right sp we never know never.
We don't know of any, but that doesn't mean there aren't any, just that we haven't found them yet.
because there life substaintals are not appropriate
the organism that feed on other living organisms
Yes, they do.
At the moment, no planets are known to have conditions similar to Earth's for supporting life. If there planets similar to Earth, there would definitely be living organisms of some sort. On the other hand, there is slightly less chance of sentinent life such as our own species existing.
free-living! We don't live on or in other organisms.
because there life substaintals are not appropriate
what makes a plante living is if it has living organisms on it
All living organisms have to have a host to create other organisms. This includes micro organisms as well as bacterial organisms
I suppose maybe... but not strong enough to form into humans, animals or any living thing. So it is impossible to live on other planets. PS, even if there were other organisms, then we would need to exclude Mercury as its too hot, Jupiter, Saturn, Uranus and Neptune as they are either too cold or because they are all gas planets.
I would think exobiology is the study of living things on other planets, though we still have not found living things on other planets.
Yes, they do.
well earth
The official definition of the word biosphere is the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms.
Almost certainly some other planets have tiny one-celled organisms, at least.
Single celled organisms are examples of living cells that are organisms. Most other living cells are parts of living organisms, but could not survive long on their own.
depending on the planet there cannot be living things on other planets
