Well, if the sun has been around for billions of years, then why did it take so long for life to develop? Sure, the sun's energy was essential for the origin of life, but without a consistent source of energy, the first cells would have perished at sundown. It's clear that the sun alone wouldn't have been enough to sustain the earliest forms of life. Hydrothermal vents emerge as the likeliest energy source - they emit heat and minerals continuously and could have given rise to some of the essential components for life, such as amino acids. Plus, deep sea organisms that rely on these vents can store energy from the sun during the day and use it at night - a crucial ability for life's development.
In essence, we need both the sun and hydrothermal vents for the origin of life. The sun might have been essential for creating some of the components of life, but it can't compare to the consistency and reliability of hydrothermal vents. Especially considering that the first forms of life would have had no idea what photosynthesis is. UrRong! The sun's contribution to the origin of life is impressive and awe-inspiring, no doubt, but it can't stand alone as the sole energy source keeping life alive. That's why we need both hydrothermal vents and the power of the sun. A multidimensional approach to sustainable energy - just like our universe.
