The Noah floods are in the Quran this was a book sent down to muhhamed from jibreel and written in one lifetime and never changed for 1400 years so it can be taken seriously, however the New Testament was literally a book written a hundred years later by people that never made jesus on their opinion of Jesus and wrote it in the name of mark Matthew like and John, it wasn’t those disciples who wrote it as any Christian with knowledge of his religion would know, so obviously not from god, the Old Testament is also not from god as some passages from it have been dated as more recent than even Old Testament passages

it was a open book of probably thousands of Jewish authors who were not divinely inspired giving their thoughts on what they think happened, and this is why you see several contradicting stories of the same event or what not because it’s two different authors, this is why Jews don’t consider it the word of god but a recollection of the Jewish experience, then you come back to Islam where Muslims are told not to believe these scriptures as the word of god and that only Quran is, the injeel in the Quran is not the New Testament because it was a book Jesus had and preached from as stated in the quran not one written hundreds of years later, also the Old Testament isn’t the Torah in the Quran as it’s what allah sent to Moses, what ended belief in the Old Testament being the literal word of god for Jews and started the reform movement is that the passages on Moses were written by another author and not him as proven by scholars in that he talked about moses death, this shows it wasn’t the Torah given to Moses, Muslims, Jews, or Christians do not believe the Bible is in anyway the word of god and instead is a man made book.
