Questions about noah ark

[user]

Why is it in the christian section? I remember having that debate with a muslim 5 years ago, and poor ignorant me was trying to explain to him that there are over 100 thousand species of of flies alone in the universe, and to just save the flies you need an arch. And him saying nu uh and Noah lived 700 years and he built it when he was 500, here I was talking about species and Darwinism and he lacks the common sense to not believe that the human race use to live millenias and that it apparently eluded all scientists etc... it was a lost fight. What a moronic prophet that lives 700 years and fails to write one book or discover anything.
