Why do we have bones in our body?
Why does the earth revolve around the sun from the same distance?
Why do we not fall down from the earth?
Why are the rivers connected with the ocean?
Why are we on earth and not on any other planet?
Why do we sweat?
Why is the sea blue?
Why oil, petrol floats on water?
Why do we wince?
Why is the moon sometimes out in the day?
