Most likely water and heat. Algae would grow, then things that eat the algae would evolve, and so on.
Liquid water is a life-sustaining substance that exists in vast amounts on Earth but not on other planets of our solar system. Water is essential for life as we know it, and the presence of liquid water is a key factor in determining a planet's potential to support life.
That is not currently known.
Earth is the only known planet that contains the necessary elements and life sustaining environment for life, as we know it, to flourish
They least resemble rocky planets like Venus Earth and Mars, particularly they least resemble planets that we would consider as possible life sustaining planets.
NO- People have found water on other planets but there is no life there.
There are several books that deal with life on other planets. Some titles include Is There Life on Other Planets by Gregory Vogt, and The Mystery of Life on Other Planets by Chris Oxlade.
Life on Other Planets was created in 2001-10.
Earth's scientist have not found life on other planets to date.
As far as is known there isn't one. Certainly there is no other planet in our solar system capable of sustaining life. It is quite likely there are other planets elsewhere which could support life but we do not have the ability to either find or travel to them.
Emanuel Swedenborg is the author of Life on Other Planets
The only planet we know for sure today is the Earth. We know that the other planets are either too cold, too hot, or have been observed to have no atmosphere to support life. It is only on planet earth that we have observed actual life. It is not impossible that primitive life can still be found on other planets in our solar system, but it will likely be very extreme bacteria etc. Complex life like multi-celled organisms do not exists on other planets in our solar system. We do not know for sure if complex life exists on other planets outside our solar system. The primary reason that we do not know, is that we have not been able to observe planets outside our own solar system.
We cannot say if life exists on other planets or not. We are trying to work it out.Just because there is no evidence does not mean that there is no life on other planets. We are trying to work out the answer but the answer maybe, YES.
