The expression "neither of Eve nor of Adam", so it would date from 1752, since everyone knows the story of Adam and Eve, created by God, at the origin of humanity, in Genesis. And this expression is used to reinforce the idea that we do not know something or someone at all, that we have never heard of them, because Eve and Adam, everyone has heard of them, everyone knows the story of Eve and Adam. So when we say that something is neither of Adam nor of Eve, well we wanted to say that it is something that is not known.
And today, we use this expression "neither of Eve nor of Adam" to say "I have never heard or never seen this thing or this person". We often add the verb "to know", we say "ne connaître ni d'Eve ni d'Adam", but it means,
Let's look at some examples as usual. The first example would be, imagine someone who is talking to another person and says to them: "This person was very familiar to me even though I don't know them from Adam." So by saying that, this person who says they don't know them from Adam, that means they don't know them at all, they have absolutely never seen them and they have never heard of this person.
Another example: "I don't want to sit turkey whatsapp number data next to her. We don't know each other from Adam. What are we going to tell each other?" Again, we don't know each other from Adam, which indicates that we've never heard of each other, we've never seen each other, we have no idea what the other person represents.
Last example, although I think it's already very clear: "He told me about a supposedly very famous actor, but I don't know him from Adam." Here, you feel the contrast. He was told about an actor, he was told: "oh this actor is very famous," and in fact, he doesn't know him at all, he hasn't seen him in any film and he's never heard of him, he says he doesn't know him from Adam, that's all.
So I think that all this is now very clear to you and I suggest that you practice your pronunciation a little. We will of course review this expression right after, but you will be able to practice your pronunciation of the sound "am", the nasal vowel "am", which sometimes poses a problem for some non-French speakers. So I will pronounce a certain number of words in "am" and you will repeat after me, I will give you a little time. Are you ready? Let's go.
