Yeah, no more than the later Jewish ones which are related to them.
What do ancient texts tell us about evolution?

Nice Elroch.
There have been thousands of different Creation stories that have come down the pipeline over the millennia.
All of them contradicting each other.
Should we teach them all as fact?

An African-Cuban Creation Story.
Olofi created the Earth and all things in it. He created beautiful things and ugly things. He created Truth and he created Falsehood. He made Truth big and powerful, but he made Falsehood skinny and weak. And God made them enemies. He gave Falsehood a cutlass [large knife], unbeknownst to Truth. One day, the two met and started fighting. Truth, being so big and powerful felt confident, and also very complacent since he didn’t know that Falsehood had a cutlass. So Falsehood cunningly cut off Truth’s head. This jolted and enraged Truth, and he started scrambling around on the ground for his head. In his scrambling, Truth stumbled unto Falsehood, and knocking him down Truth, felt the head of Falsehood, which he took to be his own head. His strength being truly awesome, a mere pull from Truth yanked off the head of Falsehood. Truth then put the head on his own neck. And from that day what we have had is a horrible mismatch: the body of Truth and the head of Falsehood.

Yes, it is clear that the Jewish myths are derived from the earlier ones from the same region in many respects. Precursors of the stories of Genesis were passed down by the Babylonians and Sumerians to the ancient Jews when they emerged later as a distinct group.
But it's also worth noting that these stories change. most names are different, the numbers of characters are different, what they do is different, what happens is different. Just some of it is common.

Firstly, it's worth noting that Jewish history extends back to about 1500 BC. Ancient Sumeria extends back to around 4500 BC. The remaining written version of the Sumerian creation myth itself predates Jewish history, at around 1600 BC.
It's also interesting that archeology disagrees quite significantly with Jewish tradition:
"Archaeology reveals a different story of the origins of the Jewish people: they did not necessarily leave the Levant. The archaeological evidence of the largely indigenous origins of Israel in Canaan, not Egypt, is "overwhelming" and leaves "no room for an Exodus from Egypt or a 40-year pilgrimage through the Sinai wilderness". Many archaeologists have abandoned the archaeological investigation of Moses and the Exodus as "a fruitless pursuit". A century of research by archaeologists and Egyptologists has arguably found no evidence that can be directly related to the Exodus narrative of an Egyptian captivity and the escape and travels through the wilderness, leading to the suggestion that Iron Age Israel—the kingdoms of Judah and Israel—has its origins in Canaan, not in Egypt: The culture of the earliest Israelite settlements is Canaanite, their cult-objects are those of the Canaanite god El, the pottery remains in the local Canaanite tradition, and the alphabet used is early Canaanite. Almost the sole marker distinguishing the "Israelite" villages from Canaanite sites is an absence of pig bones, although whether this can be taken as an ethnic marker or is due to other factors remains a matter of dispute."
The Sumerian and Babylonian myths are the most ancient texts known that tell us about the myths of ancient peoples. How much weight should they carry as evidence about the history of planet Earth?
