Non-existent. The sun is essential to the life of any living organisms on the surface of the planet. Without the sun, the surface of a planet (take Earth for example) would freeze to the point where no living thing would be able to inhabit the planet. However the presiding answer is questionable if the removal of the sun could be anticipated, a plan to excavate deep into the planet's interior regions (deeper than mankind has ever gone) and build structures within the region between the mantle and crust regions where heat from the mantle could possibly sustain life for these advanced organisms (take a guess...) that could utilize this strategy. Granted that those structures are able to sustain permanent stability under the pressure and heat emitting from the mantle.

There would certainly be no life. More though, without the Sun there'd be no Earth orbiting it!
Without the sun, Earth would be a dark, frozen place. The sun provides the energy necessary for life to thrive, so without it, plants wouldn't be able to photosynthesize, leading to a chain reaction affecting the whole ecosystem. Temperature would drop significantly and eventually life would become unsustainable.
That would be, like, "Earth". like, like, really?!
The sun is essential for life on Earth because it provides heat and light energy that drive processes like photosynthesis, which is how plants produce oxygen and food. The sun's energy also regulates Earth's climate and weather patterns, creating the conditions necessary for life to thrive. Without the sun, Earth would be cold, dark, and unable to support the diverse ecosystems present today.
Without the atmosphere, Earth would be exposed to harmful radiation from the sun, extreme temperatures fluctuations between day and night, and no protection from meteors entering the atmosphere. Life as we know it would not be able to exist without the atmosphere providing vital components like oxygen and a stable climate.
Without rotation, one side of the Earth would always face the Sun, leading to extreme temperature differences between the two halves. The lack of rotation would also disrupt weather patterns and ocean currents, impacting ecosystems and climate worldwide. Additionally, without the Coriolis effect from Earth's rotation, hurricanes and cyclones would not form as we know them.
It would be hell on earth.
There would be no life without the Sun ... Earth would be just a frozen ball of rock floating around in the dark of space.
Not a lot! Early life transformed the atmosphere; removing much of the carbon dioxide, so without life Earth would probably have an atmosphere and environment like Venus.
Humans would become excinct as we would all die! There would be no life on Earth! THAT'S WHY WE CAN'T WASTE WATER!!
ok how would the earth be like without plate tetonics
Earth could not have grown to planet size without gravity, but hypothetically speaking, there would be nothing to hold down the atmosphere, so there would be no life.
There would be no life.
The Earth would overheat by through global warming into overdrive. The Earth would become like her sister planet Venus. A world without life. Search for Venus and you will have your answer.
If there was no ozone, there would be no life. UV is fatal for life on earth.
Without the biosphere, Earth would likely resemble a barren, lifeless planet with no greenery, animals, or bacteria. Without the atmosphere, Earth would be exposed to harmful solar radiation and extreme temperature fluctuations, making it uninhabitable for most life forms.
Life would not exist.
In most probability the earth would never have come into existence without the sun. However, if the sun had to disappear now, all life on earth would die very shortly, as everything on earth requiring it's energy would die. Everything that orbits the sun will go off track and possibly collide as there will be no gravitational pull from the sun.
