Because there's not such a thing as an interventionist God.

Except the god of the bible. He did some serious intervention.

True, hundreds of years ago (theoretically), and no one is here to tell us. How very convenient. 

I'm not denying God's existence, I'm an agnostic. But if God exists, I'm sure he/she/it let us at our own free will.
