Yes, on earth.
No alien life has been found so far; either inside or outside our Solar System.
To you and me, probably very important since we live in it. I am not sure our solar system is very important to life forms on the other side of the universe.
Yes. Planet earth has many forms of life. However apart from on Earth there is no other life that we know of.
So far - Earth
Life/land forms and water

There are thousands and thousands of other planets outside of our solar system, along with many other galaxies, universes, and planetoids, and possibly other forms of life.
if there were no solar system then there would be no life?
Within our solar system at the present time, no. Regarding planets orbiting other stars outside our solar system, our present technology is nowhere near able to tell.
Currently, Earth is the only planet where carbon-based life forms are known to exist. However, the search for life, including carbon-based life forms, continues on other planets and moons within our solar system and beyond.
The solar system provides the necessary conditions for life on Earth, such as sunlight for photosynthesis and stable temperatures. The gravitational pull of the sun and other planets helps create tides essential for marine life. Additionally, the sun's energy drives weather patterns and climate, which impact the distribution and evolution of life forms on Earth.
As of now, Earth is the only planet in our solar system known to have life. Scientists have not found any definitive evidence of life on other planets within our solar system, although there are ongoing investigations into the potential habitability of places like Mars and some of the moons of Jupiter and Saturn.
