We know incest is forbidden in Islam and other religions. But when we go back to the first human being on earth, prophet Adam, we know that he had children with his wife Eve. And as we are all coming from both of them, it means at some point incest had to happen right. Maybe I am wrong but I really want to understand this aspect. Maybe there is a good explanation for it. Was incest permisssible at that time only temporary ? Or were there more than 2 human being created right after Adam and Eve
