If all people come from same ancestors, Adam and Eve, they all could have similar ideas about the beginning, and it would not necessary mean someone copied something.
Evolutionary biologists have demonstrated humanity did not start with 2 people, we developed out of H. Heidelburgensis over thousands of years.
The myths are similar because they are all found in the same area, the Middle East. They traveled as stories. They don't have them in other parts of the world. Jesus is a Greek Hellenistic demigod and the religion is very Greek/Persian.
So, you believe Genesis is copied from Persians?
No, Genesis is a re-working of Mesopotamian myths. The Persian occupation wasn't until later.
I don't "believe" it, it's what the evidence presents, I care about what is actually true, not believing what I want to be true.
The Persians allowed the exiled Kings to return and they had been exposed to these stories. Suddenly, they too had similar versions.
It's made up.

John Collins, Introduction to the Hebrew Bible 3rd ed.
“Biblical creation stories draw motifs from Mesopotamia, Much of the language and imagery of the Bible was culture specific and deeply embedded in the traditions of the Near East.
2nd ed. The Old Testament, Davies and Rogerson
“We know from the history of the composition of Gilamesh that ancient writers did adapt and re-use older stories……
It is safer to content ourselves with comparing the motifs and themes of Genesis with those of other ancient Near East texts.
In this way we acknowledge our belief that the biblical writers adapted existing stories, while we confess our ignorance about the form and content of the actual stories that the Biblical writers used.”
The Old Testament, A Historical and Literary Introduction to the Hebrew Scriptures, M. Coogan
“Genesis employs and alludes to mythical concepts and phrasing, but at the same time it also adapts transforms and rejected them”
God in Translation, Smith
“…the Bibles authors fashioned whatever they may have inherited of the Mesopotamian literary tradition on their own terms”
THE OT Text and Content, Matthews, Moyer
“….a great deal of material contained in the primeval epics in Genesis is borrowed and adapted from the ancient cultures of that region.”
The Formation of Genesis 1-11, Carr
“The previous discussion has made clear how this story in Genesis represents a complex juxtaposition of multiple traditions often found separately in the Mesopotamian literary world….”
The Priestly Vision of Genesis, Smith
“….storm God and cosmic enemies passed into Israelite tradition. The biblical God is not only generally similar to Baal as a storm god, but God inherited the names of Baal’s cosmic enemies, with names such as Leviathan, Sea, Death and Tanninim.”
Noah - Also he sent forth a dove from him, to see if the waters were abated from off the face of the ground; But the dove found no rest for the sole of her foot, and she returned
Gilamesh - . When the seventh day dawned I loosed a dove and let her go. She flew away, but finding no resting- place she returned.
Noah - And the ark rested in the seventh month, on the seventeenth day of the month, upon the mountains of Ararat. And the waters decreased continually until the tenth month: in the tenth month, on the first day of the month, were the tops of the mountains seen.
Gilamesh - looked for land in vain, but fourteen leagues distant there appeared a mountain, and there the boat grounded; on the mountain of Nisir the boat held fast, she held fast and did not budge. One day she held, and a second day on the mountain of Nisir she held fast and did not budge. A third day, and a fourth day she held fast on the mountain and did not budge; a fifth day and a sixth day she held fast on the mountain.
Noah - And Noah builded an altar unto the LORD; and took of every clean beast, and of every clean fowl, and offered burnt offerings on the altar.
And the LORD smelled a sweet savour; and the LORD said in his heart, I will not again curse the ground any more for man's sake;
Gimamesh - , I made a sacrifice and poured out a libation on the mountain top. Seven and again seven cauldrons I set up on their stands, I heaped up wood and cane and cedar and myrtle. When
the gods smelled the sweet savour, they gathered like flies over the sacrifice.
Noah - The earth also was corrupt before God, and the earth was filled with violence.
And God looked upon the earth, and, behold, it was corrupt; for all flesh had corrupted his way upon the earth. And God said unto Noah, The end of all flesh is come before me; for the earth is filled with violence through them; and, behold, I will destroy them with the earth.
Gimamesh - “Wisest of gods, hero Enlil, how could you so senselessly bring down the flood? Lay upon the sinner his sin, Lay upon the transgressor his transgression, Punish him a little when he breaks loose, Do not drive him too hard or he perishes; Would that a lion had ravaged mankind Rather than the flood, Would that a wolf had ravaged mankind Rather than the flood, Would that famine had wasted the world Rather than the flood, Would that pestilence had wasted mankind Rather than the flood
Noah - And it came to pass after seven days, that the waters of the flood were upon the earth.
Gilamesh - When the seventh day dawned the storm from the south subsided, the sea grew calm, the flood was stilled;
Noah - And all the days of Noah were nine hundred and fifty years: and he died.
Gilamesh - Gilgamesh, the son of Ninsun, lies in the tomb.
