Why was a flood needed?

if this All powerful God created the Univerese , the Earth, and made a Man out of Dust. then how come it Needed to flood the Planet to get rid of People and things it didn't like? couldn't it just think it and it would be done??? I really want to know what creationiests think about this Please answer

I just always wonder if a reasonable Explanation can be come up with when I make topics like this..... but I guess not... because creationists never respond to them........... I just like to see if it possible in the face of Being proven wrong to come up with a logical idea.......[This message has been edited by DC85, 07-06-2003]

Mike again you are missing what Evolution is . I mean you act like we are saying. one day an Ape gave Birth to a Human....... I mean really mike thats not what we are saying at all. their is a THIN line between what is human what isn't. Homo Erectus(spelling) was by Most aspects Human. same with Neanderthals(now known not an ancestor but shared a common one) was so close to Human and many other Examples . if you look into it you can see how it happened easy where as the Bible.... has little or no backing. If the Bible Had better Backing it would be science. I mean Science is Based on facts we Know then Ideas come up to Explain it.
