The Archeozoic (Archean) is the earlier eon (approx. 4-2.5 billion years ago) with the very first simple life (prokaryotes). The Proterozoic follows it (approx. 2.5 billion to 541 million years ago) and saw more complex single-celled life and later the first multicellular organisms.

Conceptual Metaphor
TIME IS A LAYERED STRATA; ANTIQUITY IS DEPTH. The Archeozoic is the deepest, most foundational layer of time.
