It's like sitting at a computer that has not had any software programming or any information placed into it. It may have trillions of megabytes of capacity. However, at this time it is empty. So man sits down and asks this empty computer to figure out the theory of relativity or asks for the breakdown of the atom. Naturally the computer just sits there with blank on its screen.
Man is the same.
Without God putting information into his brain, nothing could come. Man cannot invent something from nothing - it is impossible. However, nothing is impossible for God, so he keeps inserting these new little megabytes of information into different people and, presto, it sounds like this man in all his genius has discovered some unbelievable miraculous cure or answer to something. In all things there is but one who is the source of all knowledge and the fount of all wisdom. That is where God shows his work and man will never be able to come anywhere even close to understanding it all, let alone be able to create even any small part of it.
