Question

would we die without the sun

Answer 1

Yes, we would die without the sun but it will take a lot of time for that to happen, because the earth by its nature preserves the amount of heat energy that it absorbs from the sun daily, so the first thing that will happen when the sun is absent from the earth is the difficulty of life on the planet, plants will not be available due to the absence of the photosynthesis process that depends on it Plants are in the composition of their food, and without it wither and die and the animal that feeds on them dies, and in the end man dies because he does not find animals to eat or plants to live on.
