Hea/Ea was the Sumerian god Enki, a name meaning “Lord of the Earth” or “Lord of the Below.”
It is associated with fresh water and is considered the domain of the god Enki (or Ea), who is often depicted as a deity of wisdom, creation, and water.
The Babylonian trinity was composed of Hea, Anu, and Bel. Bel represented the sun, and was the favorite god.
The supreme triad in Babylonian/Sumerian religion was indeed Anu (sky/heaven god), Enlil (later called Bel or Belus, god of earth/storms/wind), and Ea (also Hea or Enki, god of fresh waters/wisdom/crafts/underworld).
Anu is the equivalent of the unmanifested deity AIN SOPH, while Bel is the Spirit of God or Sephira, and Hea the Universal Soul or wisdom of the three combined (SD I:357).
Scientists and Naturalists like Charles Darwin might be likened to Ninshubur, a deity associated with the natural world, or Enki/Ea, a god of wisdom, intelligence, and the creator of mankind, known for his knowledge of all things.
While Enlil and Adad were not primarily water gods (like Enki/Ea, who was the god of water, knowledge, mischief, crafts, and creation), their association with storms and rainfall indirectly connects them to the element of water.
The Apkallu are antediluvian sages praised for wisdom, sometimes called sons of Ea.

The story features Enki (Ea) and Ninmah (Ninhursag) engaging in a humorous and somewhat ribald competition to create various human and animal beings, with Enki often needing Ninmah's help to fix his creations.
In Mesopotamian tradition Enki (Akkadian Ea) is the crafty water and wisdom god who side-steps the destroyer’s plan.
Ea (Enki) is under oath not to warn mankind, so he speaks to the reed house and the wall.
The lord who gives these instructions is the god Ea, the Akkadian name of Enki.
A friendly god warns one man (Enki / Ea / Cronus / YHWH)
