Who was the wife of Cain? since the only children of Adam and Eve that were recorded was him and Abel...?

She was from the city that they met in and Enoch was born in, later named Enoch. Adam and Eve were the first people created and only ones created INSIDE the Garden of Eden. While they lived in the garden, God put some other people OUTSIDE the garden for Adam and Eve's children to meet and marry. There wasn't any like many atheists claim to.
