God in the shadows

If God is god, why does He hide in the shadows? Why does He not show himself and put an end to the myriad made up thoughts, the debate, the strong opinions, the hatred, the wars? Why does He leave his subtle fingerprints all over our universe and create this yearning in our hearts only to leave it unfulfilled for lack of usable evidence? Why does he not come to earth and show himself? It wouldn’t have to be to all of us, just a few. If they wrote it down as history for the rest of us, that would be enough, right?
