Primitive Earth Model

Definition

The primitive earth model is a scientific theory that describes the conditions and environment of early Earth, around 4.5 billion years ago.

Analogy

Think of the primitive earth model like setting up an old-fashioned movie set. Just as filmmakers create a specific environment to tell their story (like a wild west town or medieval castle), scientists use this model to explain how life might have originated on our planet under certain conditions.
