That's a great question! It's easy to get them mixed up since both Apollo and Helios are associated with the sun in Greek mythology. However, they have different roles and personalities:

Helios is primarily the personification of the sun itself. He drives his chariot across the sky each day, bringing light and warmth. His role is more about the physical aspect of the sun.

Apollo, on the other hand, is a more complex and multifaceted god. While he is associated with the sun, he also represents light, music, poetry, prophecy, healing, and archery. He is a more active and cultural god, not just a force of nature like Helios.

So, to answer your question:

* Helios is considered the sun god in the literal sense.

* Apollo is a god of many things, including the sun, but his role extends beyond the sun's physical presence.

Therefore, both are connected to the sun, but their roles and significance are different.
