Why is when we swim all the holes in our body do not get filled with water and i don't drown to death.
Why can i take a bath and my belly button ears nose and butt do not get filled with water and i drown to death.
Reason
God had knowledge that holes get filled with water.So he used this knowledge and designed our body holes to let stuff out but not back in.
This used knowledge fits perfectly with the definition of intelligence.
intelligence
The ability to acquire, understand, and use knowledge.
This is proof the creator used knowledge.
