Strange Creatures on Island

There are people and strange monkeys on this island, and you can not tell who is who (Edit: until you understand what they said - see below). They speak either only the truth or only lies.

Who are the following two guys?


A: B is a lying monkey. I am human.


B: A is telling the truth.


Identify the creature!

Know who are they! 

 

Identifying the Strange Creature


What was the situation?

 Let's first have statements by 2 creatures

A: B is a lying monkey. I am human.

B: A is telling the truth.


If we assume B is telling the truth then A is also telling the truth. But A in statement says B is lying which contradicts our assumption. 

Hence, B must be lying. If B is lying then statement of B suggest that A is also must be lying. That mean 'B is lying monkey' part of statement made by A is too lie. Since we have deduced already B is lying, the lying statement of A suggests that B is not monkey. Hence B is the lying man!

Other lie spoken by A is that it is human. Hence A must be a lying monkey!
