That would be God. Secondly, the hard sciences are not the only place one can look for evidence. The writings of Scripture, completely aside from whatever historical value they do or do not have, make certain statements about the character of God, of humans, and of the world, statements which are borne out by my observations of people and the world, and my personal experience of getting to know God. Some of the evidence presented on those topics is very hard won - Solomon's Ecclesiastes, for example. What I was trying to say last year was merely that there is no absolute proof either way - there is no proof that God exists, there is no proof that he does not.
Evidence is a different story.
There is a rich and vast body of evidence, in many domains, to support the idea that there is more to this cosmos than meets the blinking eye. Be sure to include your name and affiliation.
