What on earth are you talking about. They explain almost all of that (including the flooding part), and what they don't explain is for a very good reason (it'll be told in future Zelda titles).
Seriously man, this is really sad. You're always complaining about plot holes in games that you never finished. PERHAPS THEY'RE NOT ACTUALLY PLOT HOLES AND THEY ACTUALLY GET EXPLAINED LATER ON IN THE GAMES.
