9 mothers?

 I want to find a riddle I can actually figure out and have the satisfaction of having someone who knows if I am right or not tell me. Lately, I have gained so much respect for the makers of Cross-word puzzles. It is not just showing off your random, otherwise useless knowledge like I supposed. It takes soon much intelligence to create a puzzle that works with wrong words to suggest other wrong words while being an actual clue for the right word. Difference between those puzzles and life is that it tells you if you are wrong, even if it works fine.

OK, so I was thinking about my mother and about my children and then about, strangely enough Loki or anyone who is said to have multiple mothers. There are many ways that it makes sense to me, but ultimately I went with one way that fit with the other words that I solved supplying several hints and such. My conclusion was that our notion of what a mother is confuses us. Our idea assumes the communicators were saying that the person received biological instructions to become a likeness of them, wait, hey, someone said that I looked like my mom, but that does not make her my mother. Several someone's said that I looked alot like Bridget Fonda, but she is not at all my mother. I have read several comments regarding biology not being the sole determiner of parenthood, but why then have biological paternity tests or classifi actions. If it were not a thing. Oh, it is a thing, just not THE thing that defines a mother or father.

The reason why having many mothers is problematic is that we define a mother as being one who births a child...oh, but what about surrogates, is their title still mother, why yes, it is. See? We are making a thing confusing by assuming we know what it means, but how would we ever KNOW if we were correct?
