Could we assume that PIE *dHeg^Hom "earth" and Semitic 'DM "earth are cognates? Could we infer a common Nostratic source? Or some mutual influence? In both languages there's the pair earthly being (human)/earth, cf. homo/humus and adam/adamah. Is there another language where the word for "man" mean "earthly"?
