When God created heaven and Earth, he also created Adam and Eve. In fact, since he liked women better, he not only created one Eve, but more. Two, three,... on the ninth day, he had created more than 10 billion of them. All looked differently, smelled differently, sounded differently, behaved differently, and pleased Him differently. But all were of divine beauty and gifts.
But since even He ran out of names for this legion of women, he decided to number them: eve1, eve2, eve3, and so forth, until he reached even.
