It is quite possible. Billions of years ago, the Sun was a lot cooler. Life may well have existed on Venus because of this. However, because of changes in the atmosphere - a severe global warming, any life that did exist, perished. For low values of "billions," the answer is definitely yes, as there are fossils from life on Earth from two billion years ago.
What else can I help you with?
Is there life of on other planets?
Well, no life on other planets has been proven, but it would be ignorant to think that Earth is the only planet among billions of star systems in the milky way galaxy, which is one of the billions of galaxies in the universe. The planets other than Earth that most likely have life in our solar system is Mars because it is in the Goldilocks zone of our solar system, which means there is the ideal temperature for an atmosphere and liquid water.
Is there another habitable planet in the solar system?
Earth is the only habitable planet in our solar system. As for the rest of the universe, it's highly probable that there are planets that can sustain life but compared to the billions of other objects in that vast emptiness, it's a difficult task to even find any.
What would happen if there was no solar system?
if there were no solar system then there would be no life?
Are there solar systems in Andromeda galaxy?
We don't know for sure - Andromeda is just too far to see that small detail. However, from current understanding of solar system formation, there will be billions of solar systems, planets and probably life .
Are there more suns outside the solar system?
Yes. There are many stars outside our solar system. Our galaxy, The Milky Way, is home to a very small number of the stars in the universe. In fact, most the stars you see in the night sky are far beyond our solar system. There are billions, even trillions of suns out there, and it's even possible that some could support life.
What location within your solar system can contain life?
20light years away there is a planet that may contain life its called Gill
Where did life start?
Life first began in the oceans, billions of years ago.
Is life possible on any other planet?
Quite possibly. So far, scientists have discovered over 1,000 planets outside our solar system, and estimate that there are hundreds of billions more in our galaxy.
The solar system is only one of millions of solar system in the universe could there be life in every solar system?
Not on every solar system. For life to exist in a solar system, there has to be at least one planet in the system, capable of supporting life. It must be not to big or too small, not so close to its star that it would be too hot, nor so far from the star that it would be too cold. Scientists still do not know the composition of an average solar system, so they do not know how often the conditions for life would exist. In fact, scientists do not really know at what extremes of temperature and gravity, or in what atmospheric environment life could evolve. They do know that solar systems must be quite common, since so many planetary discoveries have been made in just a few years. In all probability, there are many millions, even billions, of solar systems in the universe. Some of these will support life. In some of them, advanced forms of life must have evolved. And if there are advanced life forms out there, some must have evolved civilisations far beyond those on earth. Perhaps they have created religions of their own, or perhaps not. They may even have created religions in the far distant past, but now only see their religions as relics of a more primitive past.
What is special about your solar system?
It's the only solar system we can confirm has life on a planet.
What make earth unique in your solar system?
The Earth is unique in our solar system because it is the only planet that has life on it. It is the only planet in a viable position to support life (other than bacteria), the only planet with water on it, the only planet with a good atmosphere to keep heat and cool in, and the only planet with the perfect combination of elements in the atmosphere to support life.
Is earth the only planet that holds life?
In our solar system, Earth is the only planet to support life. But there has been some speculation that entire communities of bacteria could exist under the surface of Mars, but that's just speculation and there's no proof. But outside of our Solar System, there's almost certainly life, both primitive and intelligent. There are hundreds of billions of star systems like our own solar system in the Milky Way galaxy alone! And there are hundreds of billions of galaxies in the Universe! Even if the chances of a planet supporting life are very slim, it is safe to assume that there is life in millions of other planets. But most of these planets that support life don't necessarily have intelligent organisms, like us humans. Most of them just probably have bacteria, or other small organisms.
