The Greeks god of the sun was Apollo and that was the name given to the US space program that landed men on the moon.
Zephyrus (Ζέφυρος) was one of the Winds (the winds were gods in greek mythology) and the god of the west wind.
The Greek word for sun is helios.
At Greeks time, it was not mythology but now it is. For the ancient Greeks, it was their religion, now it is a collection of interesting stories.
I don't know about in modern times, but in Ancient times, virtually all Greeks believed in their gods, which we call Greek Mythology. For the Greeks, their religion was much more important in their lives than religion is for many people today. In fact, their religion was a lifestyle for them. As for modern days, I'm hazarding the guess that there are a lot less people who are greek or live in Greece that believe in ancient Greek Mythology. Hope I helped! :)
The Greeks did not date their mythology.
