Decisive evidence that numerous life forms exist in the universe

‌Water is the origin and essential source of all life.
Even in our small solar system, numerous planets possess water,
and we do not know what exactly exists within that water.
Recently, Saturn's moon Enceladus was found to consist of the three components necessary for the existence of life.
Furthermore, a recent study was published showing that when water was created under the same conditions and composition, life from Earth could survive.
Since water is abundant on planets even within our solar system, the same is likely true for other solar systems.
We must assume that life exists in some form, whether as organisms or otherwise.
NASA: "9 celestial bodies in our solar system containing water"
“Jupiter's moons Ganymede, Callisto, and Europa; Saturn's moons Titan, Mimas, and Enceladus; Neptune's moon Triton; and the dwarf planets Ceres and Pluto.”
On the 11th, NASA (National Aeronautics and Space Administration) released an infographic revealing 9 celestial bodies throughout our solar system that contain water and oceans, and may even harbor life.
NASA scientists stated, "Our solar system is full of water."
On Jupiter's moon Europa and Saturn's moon Enceladus,
these oceans appear to consist of the three components necessary for the existence of life as we know it.
These are energy sources that can be used by living organisms and chemical elements essential for biological metabolic processes.
It was announced that Mars was once a planet filled with water.
Jupiter's moon Callisto, Saturn's moons Titan and Mimas, and Neptune's moon Triton
are also thought to have large oceans beneath their surfaces.
NASA scientists believe that there is also water on Triton, Neptune's largest moon.

It is said that there are at least approximately 200 billion Earth-like planets in our Milky Way galaxy. Wow.
