Thea means goddess — from the Greek thea, the word for a female deity. In Greek mythology, Theia was a Titan goddess of sight and shining light, mother of Helios (the sun), Selene (the moon), and Eos (the dawn). Four letters that carry the entire Greek cosmos: sun, moon, and dawn all born from Thea. It's also a short form of Dorothea and Theodora, both meaning gift of God.

Greek roots
Thea comes from the Greek thea, meaning goddess. In Greek mythology, Theia (also Thea) was one of the twelve Titans — the goddess of sight and shining light. She was the mother of Helios (sun), Selene (moon), and Eos (dawn), making her the source of all celestial light. The name also functions as a short form of Dorothea (gift of God) and Theodora (gift of God). Thea has been climbing the US and European charts rapidly, part of the trend toward short, strong, mythologically rich names.
