To conservative Christians, Genesis is inerrant: it is completely truthful and contained no error in its original form. God inspired Moses to write the book and preserved him from including any errors. Thus the Noahic flood really happened exactly as stated in Genesis. The similarities between the Babylonian and Hebrew texts were probably caused by two factors:
both were accounts of the same worldwide flood.
The Genesis account is absolutely true and was written during the Exodus of the Jewish people from Egypt. The Babylonian account was written later; its author may have copied elements from the Hebrew story.
"The Epic of Gilgamesh, then, contains the corrupted account as preserved and embellished by peoples who did not follow the God of the Hebrews." 7
