I assume by "early" you mean classical since that's the earliest we have any detailed information about.

Now this is tricky because beings came in all sorts of forms in Greek mythology. For example the first divine beings such as Uranus (which is also the attic greek word for "sky") seemed may have actually beem the sky as well as personifying it. But it's unclear.

However in actual Greek religion these primordial beings weren't actually directly worshipped, their descendents the Olympian gods were. The Greeks clearly understood their gods as anthromorphised beings that represented and had control over aspects of nature but were not actually that thing.

For example Hesiod explains quite clearly how lightning was forged and used as a weapon by Zeus in the Titanomachy. It would also get kinda weird when you get to gods such as Poseidon who can represent such incredible varied things such as both the sea and horses.
