Everyone is claiming Sarada is an experiment...... but when has Oro ever created human life? He has only experimented on it. He literally kidnapped Konoha children and injected them with Hashirama's DNA. Yamato was not a test tube child, he was a Konoha citizen that lived through this experimentation. This means he was born of a mother and father.
Is Sarada's lack of a birth certificate the only reason people believe this? She was more than likely born in another village or born while on a mission of some kind, which would prevent her from being on Konoha's record. Perhaps there was even a level of secrecy involved in her birth for some reason (like Kushina giving birth to Naruto outside the village) and thus her record was omitted. I mean do people really believe this....?
