Extraterrestrial life.
The speculative study of life on other planets is called astrobiology. It is a multidisciplinary field that combines aspects of biology, astronomy, and geology to understand the potential for life beyond Earth.
there would be no life on earth because the sun supports life on earth and gives warmth to the living creatures in earth. if the sun was gone, earth would be totally dark and there would be no life there.
If there were no producers on Earth, such as plants and algae that convert sunlight into energy through photosynthesis, life on Earth would not be sustainable. Producers are at the base of the food chain, providing energy and nutrients to other organisms. Without them, there would be no source of food or energy for consumers, leading to the collapse of ecosystems and the extinction of most organisms.
Earth is currently the best planet for human life due to its ideal conditions such as the right temperature range, water availability, and oxygen levels. Other planets in our solar system lack these essential factors for sustaining human life.
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.
It could be called extra-terresrtial, or even alien
It is still called life it is just called extraterrestrial life
So far no other life have been discovered beyond Earth but the generic term for such lifeforms would be 'aliens'.
no there is not life out there becuase if there was they would have already invaded earth after thousands of years .
The source of energy for almost all life on Earth would be the sun, as it gives society today the much needed power in order to operate electricity and other forms of technology sought after to survive.
a miracle
it would break the natural web of life and all human and all other life forms would very soon die off
to study it and they would see if there is life on other plants not just earth
Life which does not originate from planet Earth may very well have developed on other planets. There is really no other explanation for where it would have come from.
If the Earth wasn't present, life as we know it would not exist. Earth provides a habitable environment with the right conditions for life to thrive. Additionally, the absence of Earth would disrupt gravitational forces in our solar system, affecting the orbits of other planets and celestial bodies.
So far we have found no planet other than Earth that is suitable for human life.
One - one side of Earth would be in constant daylight, while the other side would be in constant darkness. Two - life as we know it, would not exist.
