Identify the sphere wher life first emerged on earth hydrosphere, lithosphere, atmossphere

you're answer would be hydrosphere

Explanation:

Life on Earth, emerged in the hydrosphere, at least from the findings and data so far. The reason for that was that the atmosphere and the lithosphere were still in a faze were they were not very hospitable for any living organisms to develop. The hydrosphere, or the water bodies, on the other side, were enabling conditions for life, not perfect or as we have today, but still reasonably good, so the life started developing into the water environment, and after the atmosphere and lithosphere changed over time, it spread on them as well.
