Prophet Idrees In Quran
Regardimg mythical stories, well there are ones that authors write using their imagination and the true ones are from Allah. Just imagine size of universe, size of subatomic particles , number of stars , how human body works and infinite number of unimaginably great thinks. All bigger than any myth any writer could imagine but Allah has created those. So why the surprise if Noah lived 950 years. Anything is possible with Allah. It is just that we need to make sure we are reading the word of Allah, not an imagination of a human.
