Question

Why we two
wo ears answer it if you can

Answer 1

We have to ears to interpret the direction from which the sound is coming from.

Answer 2

We have two eyes so that we get 3 dimensional and depth perception. Also there is symmetry in the structure of the body. There is one to function well even if one eye has some problems.

Same way, two ears help us to know the direction and distance from where the sounds come. If one ear grows weaker the other works. For beauty and symmetry two ears are better than one.
