Titans are elements of the creation. E.g. Gaia is the earth. Ouranos is the sky. Kronos is time. Oceanus is the ocean.
Titans aren't gods. The difference can be demonstrated like this... Poseidon is the Greek's god over the ocean, while Oceanus IS the ocean. Gods rule and bring order to their domain. Titans are primordial forces of nature - not orderly but chaotic. In Greek myths, giants are the offspring of the two first titans - Gaia and Ouranos.
In the Amorite pantheon, which is much more similar to the Biblical accounts, Rephaim (giants) are deceased ancestors who have been elevated to the level of deities.
Titans were born of Uranus as were the Olympians, they were all somewhat related.
Still does not deny the potential link does it.
And Peter also describes the fallen ones as being chained in dungeons in Tartarus.
You were not alive back then to say one way or the other how those myths got started.
Myths can have a basis in reality.
A Nephilim Giant would have seemed godlike back then and their gods were very much violent and of the desires of the flesh, powerful things like human beings. They married, killed, fought wars, had sexual affairs, and an ordered hierarchy of powers, all the lusts of the flesh.
In
Greek mythology, the
Titans (
Ancient Greek: Τιτᾶνες
Tītânes;
singular:
Tītā́n) were the pre-
Olympian gods.
[1] According to the
Theogony of
Hesiod, they were the twelve children of the primordial parents
Uranus (Sky) and
Gaia (Earth). The six male Titans were
Oceanus,
Coeus,
Crius,
Hyperion,
Iapetus, and
Cronus; the six female Titans—called the
Titanides (Τιτανίδες) or
Titanesses—were
Theia,
Rhea,
Themis,
Mnemosyne,
Phoebe, and
Tethys.
After Cronus mated with his older sister Rhea, she bore the first generation of Olympians: the six siblings
Zeus,
Hades,
Poseidon,
Hestia,
Demeter, and
Hera. Certain other descendants of the Titans, such as
Prometheus,
Atlas,
Helios, and
Leto, are sometimes also called Titans.
The Titans were the former gods: the generation of gods preceding the
Olympians. They were overthrown as part of the Greek succession myth, which tells how Cronus seized power from his father Uranus and ruled the cosmos with his fellow Titans before being in turn defeated and replaced as the ruling pantheon of gods by Zeus and the Olympians in a ten-year war called the
Titanomachy ('battle of the Titans'). As a result of this war, the vanquished Titans were banished from the upper world and held imprisoned under guard in
Tartarus. Some Titans were apparently allowed to remain free.
