Life with no alphabet

Personally i think life without the alphebet would be horrible. Not only because we wouldnt be able to spell anything, but how would we talk? Would we just bable something hopeing the person were talking to would understand what i am trying to tell him? Or would we have to just do things ourselves instead of trying to comunicate with eachother to do it? How would we come up with words? Would we write squiggle lines and say that this means "Hi" or this means "Bye" how would be even know how to spell it or say it? I mean without the alphabet all we would have is our own minds to come up with crazy ideas trying to form words without using the alphabet. This would possibly be one of the simplest but yet worst things that would change the world and the way we are today.
