You have the theory of evolution which deals with life and changes in organisms. It is separate from abiogenesis which is the study of the origin of life from naturally occurring chemicals. It is also separate from the Big Bang theory of the formation of the universe. There is nothing in the theory of evolution about spontaneous change without a cause. It does not contain any observation of something coming from nothing. It is all about reasons for change.
This entire article consists of making up definitions for scientific theories that are so nonsensical that no one would accept them. Anyone who believes this article has no idea about the philosophical basis for the scientific method nor could they possibly understand the practical application of that method.
The point the author makes is that evolution of life, the origin of life, as well as the origin and development of the universe rely on the same basic underlying process. That being random asssociation of material and some preferential selection for survival of certain “associations” as a result of natural forces.
