Astronomers have found Earth-sized planets in other solar systems.
Earth's scientist have not found life on other planets to date.
We believe in the existence of extraterrestrial life because of the vastness of the universe, the discovery of planets in habitable zones, and the possibility of similar conditions to Earth on other planets.
Scientists study archaebacteria because they are capable of surviving in extreme environments similar to those found on other planets. By understanding how these organisms thrive in harsh conditions on Earth, researchers can gain insights into the potential for life to exist in similar environments elsewhere in the universe. Archaebacteria also provide valuable clues about the origins and evolution of life on Earth.
Yes, only on the Earth. We don't know if the other planets have life
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.
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.
Other planets do not have water nor life
Fortunately for the other planets, Earth is the only one.
Probably. Astronomers estimated that there are at least 100 billion planets in the galaxy, a good number of which may be similar to Earth. It seems pretty unlikely that Earth would be the only planet to develop life.
well the Earth is not exactly the same to other planets actually, it is the same because they're all parts of the solar system and they pretty much spin in the same direction but their features/characteristics are not much similar. Neither it is in size nor in appearance sooo....Hope this helps !!
Because Earth is the only place where we can murder the English language and ask questions like, "Why life is possible only in earth not in other planets?"
earth has air , water and life.
