Absolutely. If the goal is “What are the oldest stories that I could actually enjoy reading?”, rather than simply the oldest surviving texts, I'd rank them roughly like this.

My recommended reading order

If you're interested in stories as stories, I wouldn't read them strictly chronologically. I'd go:

1. Gilgamesh → 2. Sinuhe → 3. Shipwrecked Sailor → 4. Atrahasis → 5. Iliad → 6. Odyssey → 7. Greek myths → 8. Mahabharata → 9. Ramayana

That gives you a fascinating progression from Sumerian storytelling → Egyptian literature → Babylonian myth → Greek epic → Indian epic.

One fascinating thing

Gilgamesh is especially worth reading alongside the Iliad.

Gilgamesh and Achilles are separated by well over a thousand years, yet both are stories about exceptionally powerful men confronting the fact that human beings die.

Gilgamesh begins by wanting power and glory. After Enkidu dies, his whole outlook changes. He becomes obsessed with the question:

“How can I escape death?”

Achilles, meanwhile, knows that his heroic life is likely to be short. He has to choose between a long, obscure life and a short life of immortal fame.

That's one reason Gilgamesh feels astonishingly modern.

If you want just one book to buy: get a good modern translation of The Epic of Gilgamesh, preferably one that includes the complete surviving poems and some background notes.
