In our solar system, only planet Earth is known for its abundance of life. There may be life in the subsurface water oceans discovered on the moons Europa, Titan, and Enceladus, warmed by tidal heating, but that has yet to be confirmed.
if there were no solar system then there would be no life?
It's the only solar system we can confirm has life on a planet.
There is no known life anywhere in our solar system except on Earth.As currently defined our solar system only has 8 planets.
No alien life has been found so far; either inside or outside our Solar System.

Life?
That is a mystery my friend, is it not?
You. Me.
The sun is the source of light and heat in our solar system. It is a star located at the center of the solar system, and its energy is essential for sustaining life on Earth.
Up to now, Earth is the only planet in our solar system that can sustain life as we know it.
There is no other planet in the Solar System that can, without assistance, support human life.
There is no "second smartest" planet in the solar system. By a stretch, Earth may be regarded as the "smartest" due to the presence of intelligent life. However, since it appears that no other planets in the solar system have life, they are all equally "not smart."
