The idea that molecules-to-man evolution contradicts the second law of thermodynamics is a common misconception. The second law of thermodynamics states that in a closed system, the total entropy (or disorder) tends to increase over time. However, the Earth, where life exists, is not a closed system. It receives a constant influx of energy from the sun, which allows for the organization and complexity seen in living systems.
Life on Earth is not a violation of the second law of thermodynamics because living organisms are not isolated systems. They can acquire energy from their environment and use it to maintain and increase their internal order, complexity, and organization. While entropy may increase in the surroundings or other parts of the universe, the local decrease in entropy within living systems is offset by the energy input and the release of waste heat.
The formation of the first living cells is still an area of active scientific research, and the exact mechanisms are not fully understood. However, many hypotheses propose that the formation of early cells may have occurred through a gradual process, starting with simple molecules and self-replicating systems, eventually leading to the emergence of more complex life forms. While the exact details are not known, the presence of an energy source, such as sunlight or hydrothermal vents, provides a possible explanation for the local decrease in entropy required for the development of life.
It's important to note that the formation of life does not violate the second law of thermodynamics because the second law applies to closed systems, and living organisms are open systems that can exchange energy and matter with their surroundings.
