When explaining the faith to non-religious, non-christians, they almost always try to explain everything in the natural.
It is almost impossible to get through to them, because they don't believe in the super natural.
I had a conversation with an atheist and he said that Noah could not of fit all the animals on the ark and he could of not feed them all.
I serve a super natural God, he could of transported them into the ark as babies and then slowed their metabolism down for all I know.
I should asked him if he believes in the super natural.
