If you read the bible and believe what you see in print to be the 100% truth of earth and human history, then you have to believe that god made some others too in some lands not so far away, because we're told that Cain found a wife other than Eve with whom to sire some offsprings, or else, he did sex with a sister.  In that case we all would be descendant of incest.  Now, doesn't that just make you feel all warm and fuzzy!\n\nIf, indeed, god made some more people in some lands near and far away, we're told nothing about when it was done,  nor of anthing else concerning them.
