World Map

I started an account in Creative Mode and used a map. I created the maps from 0 - 4, 4 being the largest scaled. When I was exploring to fill the map, I accidently tossed it and it fell into ocean. Tried as I might, I could not find it. So I go to explore a new map and that map is #6. I bring out a crafting tabling and try to crated back to the maximum zoon level but it does not craft. It makes numbers of maps when I add paper and the map number goes up. I am now on map #25 and the zoom will not go bigger then map #0. It is very frustrating because I need to find my way back to my home!
