Life Without ABC's

I believe that life without ABC's would be crazy. If we were to not have the alphabet the whole world would be hectic. If we did  not have the alphabet then we wouldn't be able to do really anything. No one would know the meaning of letters so how would we even compose a simple sentence let alone a simple word? The alphabet is what helps us understand each letter individually and we are then able to come up with words and write out sentences by knowing each letter of the alphabet and the sound that each letter makes to correspond it with what word we are trying to write out. You would simply not be able to do the most important things in the World without knowing the Alphabet or without the whole ABC's even existing at all.
