How does life evolve on Earth if pre-biotic chemistry can’t explain how the complex molecules that make up life occur spontaneously in nature? This paper presents the first part of a comprehensive theory of heat transformation, focusing on the pre-biotic Earth and the role of heat dissipation and order in driving the emergence of complexity. The study challenges traditional assumptions of a biological singularity and the unlikelihood of life, proposing that life is an inevitable outcome of sustainable planetary systems. The theory utilizes the concept of dissipative structures (DSs), matter organized into heat engine cycles that grow and organize while dissipating heat. Using the laws of thermodynamics, the paper develops models to explain how heat dissipation through conservative force fields results in both entropy and order. The tropospheric water cycle (TWC) and tropospheric air cycle (TAC) are analyzed as gravitational dissipative structures (GDSs), providing examples of the massive mixing of matter and heat delivery that occurs in the gravity well of Earth. Part I of the development of a theory of heat transformation concludes with insights into the concept of negentropy proposed by Erwin Schrödinger and the nature of entropy in the universe.
