Another insight on this topic from NIDOTTE:
On the entry ofאָדָם under the OT section
8. According to Mesopotamian myth humanity was made out of divine blood (e. g., ANET, 68). The Heb. word for "blood" is דָּם (H1947), and it sounds much like the Heb. words for "man" (אָדָם) I, "earth" (אֲדָמָה), and "likeness" (דְּםוּת). Possibly by prefacing the fact that God created humankind in/according to his likeness with God created mankind in his image (צֶלֶם) (Gen 1:26), the biblical writer is rejecting the idea of creation of humanity from divine blood. Any likeness that the created bears to his Creator has nothing to do with the blood flowing in his veins (Miller).
