How Did Molecules Give Birth To Life?
Even while it is hard to describe life and all of its complexities solely in terms of the chemical makeup of its most fundamental components, that is ultimately how it all began. As atoms and molecules randomly interacted with one another in just the right way to generate the first organic substances, such amino acids, simple sugars, etc., that now make up our cells, the first stages of the origins of life on Earth required only chemical processes.
One of the major unsolved problems in evolutionary studies is how exactly that happened. We have never discovered any natural phenomena that contradicts the rigorous requirement that there must already be some pre-existing life in order to create additional life. Despite numerous attempts, scientists have never been able to create organic materials in the lab from non-organic ones, but the earliest living cells managed to achieve so. It's one of those big mysteries of life that, despite numerous ideas attempting to explain it, we'll probably never be able to resolve.
