It’s interesting to read the religious thought process on working around this particularly sticky subject. Everything from god sending down more women from heaven so that Abel could have babies and then they could all shag their cousins, to, well… god created more people than just Adam and Eve to begin with, it’s just that Adam and ever were the only two in paradise.
The idea that God made Adam and Eve in his own image and gave them a special place in the Garden of Eden does not preclude the idea that God made other humans who were not so favored. Seen this way, Adam and Eve were given favored treatment but broke the rules, and so they were tossed out into the wider world to make their way among the unchosen peoples.
