I am sorry I don’t have an Arabic keyboard, so I will write in English

I read an Article for you that says that the Flood of Noah peace be upon him was Local, but how do you deal with this Aya:

وَآيَةٌ لَّهُمْ أَنَّا حَمَلْنَا ذُرِّيَّتَهُمْ فِي الْفُلْكِ الْمَشْحُونِ

That Aya means that all the people alive now are from those who were on the ship, which means that Flood killed all the people on Earth, right?

The same thing goes for:

إِنَّا لَمَّا طَغَى الْمَاء حَمَلْنَاكُمْ فِي الْجَارِيَةِ
