In a scientific point of view certain criteria must be sustained in order for life to exist, it must be able to sustain human life in size and also have the right chemical composition of gas like oxygen, also it must contain water in order for us to survive and desirably some sources of food, without these we would die, it may be possible in some planet for life to exist but we do not know about it yet, so life COULD exist on another planet, it just needs to stick to this criteria and many planets don't so that is why life is less likely.

What else can I help you with?
Is a planet with stronger gravity more or less likely to have an atmosphere?

What is the biggest river on Mars?
There are no rivers on mars. It is a completely life-less planet.
What best determines if a planet orbiting a sun is likely to have life on it?
Water,carbon oxygen
Besides Earth astronomers believe they are most likely to find evidence of life on what planet?
Mars
What planet Mercury Venus or Mars is most likely to support life now or in the past?
MARS.
When the sun explodes and everything is gone will another planet like earth form?
Possibly, but the new planet will not have any life forms. (Most likely.)
Planet most likely to support life?
Earth is the planet most likely to support life in our solar system due to its suitable distance from the sun, presence of water, and protective atmosphere. Conditions such as temperature, atmosphere composition, and presence of liquid water are key factors for supporting life as we know it.
A planet that is most likely to have had life?
Mars is the planet in our solar system that is most likely to have had life in the past. Evidence suggests that Mars once had liquid water on its surface, which is a key ingredient for life as we know it. Additionally, there are signs of ancient river valleys, lakes, and even possible microbial fossils on Mars.
What planet Mercury Venus or Mars is most likely able to support life now or in the past?
MARS.
What planet is known to have an intelligent life?
So far, Earth is the only planet known to harbor life, much less intelligent varieties of it.
How does the temperature of the planets vary with the distance from the sun?
The further a planet is from the sun, the less light and heat radiation it gets from the sun leaving it a cooler planet. However, a planet with a gaseous atmosphere is less likely to radiate away the planets heat so it may retain more of the solar heat.
