Based on purely statistical arguments, many scientists hold the opinion that life
outside the earth is very likely.
But no evidence of it has ever been observed yet.
If it exists at the present time, we are completely unaware of it.
Depending on an extra-solar civilization's stage of cultural and technological development,
it may or may not be aware of our existence, although the times and distances involved
make it very unlikely.
liquid core
It has dogs, fish, trees, people, and cars on it.
earth is the only planet known to man which has life but there is a huge possibility of life or a different type of it existing on another planet.scientists are contantly working to find life on another planet
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.
The "Goldilocks planet" refers to a planet that is situated at just the right distance from its star to potentially support liquid water on its surface, which is a key factor for life as we know it. While there are candidates that fit this description in various solar systems, Earth is currently the only confirmed Goldilocks planet in our own solar system.
So far as is known to date there is no life on any other planet in our solar system or elsewhere. That does not rule out the possibility that life may exist on other planets
beause earth is the only planet which has oxygen and other needed sudstances .
1 . Earth is the only planet where life is known to exist..there is no other planet where life can exist !!2. Earth is the third planet which nearest to the sun and it has an atmosphere which consists of hydrogen ,oxygen and carbon dioxide which are required for the existence of human life whereas other planets do not have any such gases!!!
No life has been discovered on other planets yet. However, given the huge amount of planets in the Universe, and the fact that hardly any planet has been thoroughly investigated, it's quite possible that life does exist.
As far as what we know today, there is no life on any planet anywhere, except the Earth.
Would life exist on what planet? Earth? Mars? Yes, even if not human, trees and plant vegitation
Water
Yes
Earth is the only planet in the solar system where life is known to exist. It has a unique combination of conditions, such as liquid water, a stable atmosphere, and a suitable temperature range, that support the diverse forms of life found on our planet.
planet earth
elth olay has it
yes
