Before the turian galactic expansion, the worship of Titans used to be more widespread. Titans are described as gaint creatures that roamed the planet back in ancient time, and left their footprints behind—a common theory that those titans might have been the reapers visiting to gauge the development of turian civilisation.

Greek mythology also has Titans in it, ones that have been said to bring entropy upon the earth wherever they roamed, tyrannical and destructive, the forefathers of the greek gods of which they came and eventually usurped.

And we know that by the Stone Age of humanity, the reaper attack hasn't occurred just yet; by that time, protheans were still around and kicking, observing humanity from Mars.

The Stone Age ended between 4000 BC and 2000 BC. The widespread oral poetry that helped pass down the myths we now know as greek mythology started around 1800 BC to 1701 BC.

This offers a window ranging from 2,200 to 299 years in which the reapers invaded and defeated the protheans before roaming the rest of the galaxy and observing the infantile sentient civilisations.

It's very possible that both the turian Titans and greek mythology Titans originated from tales of the reapers in the world of Mass Effect.

And if I'm allowed more creative liberty, I'd say some tales of the mythology gods wars were heavily inspired by witnessing the reaper/prothean conflict on Mars, with the planet being very visible to Earth dating back to the ancient Egyptians. The explosion of ships in space, the red lasers of reapers splitting the sky. It does imply that the addition of titans into mythology is a late one which came after the Olympians' myths.
