I frequently hear accusations of biblical plagiarism in the old testament. The one I hear the most is that the noachian flood story takes inspiration directly from much older Sumerian and Mesopotamian myths. Is there any truth to this?

Quite a few times, I come across videos on youtube where Noah's flood is said to borrow from, or in some other way recycle, various components of Sumerian and Mesopotamian folklore that is much older than the writings in the book of genesis. I have looked into the validity of this claim, briefly, and am having a hard time verifying if it is true or not. So primarily, I want to know if this claim is accurate but I am also wondering if there is a standard by which historical claims may be verified for accuracy?

Thanks for the responses! I am an atheist so I personally no not believe the flood itself is historically accurate. I just just don't want to spread information without knowing if it is true or not. I try not to get caught in echo chambers of my own way(s) of thinking. I suppose the oral traditions of all of the aforementioned cultures are subject to their own form of change over time just like anything else. Thank you again for the responses!
