The most convincing argument for the existence of God

This is a follow up to my previous post regarding an argument against the existence of a Christian God.  It should be obvious that by "convincing," I mean convincing to me.  Anyways, here's the argument.

1. Human beings are fundamentally different from all observed entities in the physical universe.
2. If human beings are fundamentally different from all observed entities in the physical universe, then their origins cannot be completely explained by appeals to the physical universe.
3.  Therefore, the origins of human beings cannot be completely explained by appeals to the physical universe.

Of course, this argument does not show that a Christian God exists.  It doesn't even conclude that any kind of God exists.  It does, however, present a first step towards establishing that God exists.  At the very least, it shows that there is something other than the physical universe out there.

I would imagine that most people would reject the first premise of the argument.  Here's another argument given in support of the first premise.

1.  Human beings experience transcendental emotions.
2.  The fact that human beings experience transcendental emotions is best explained by the notion that human beings are fundamentally different from all observed entities in the  physical universe.
3.  Therefore, it is likely that human beings are fundamentally different from all observed entities in the physical universe.

Transcendental emotions are emotions whose scope is greater than regular social contexts.  We experience hope, despair, gratitude, and anxiety at a mundane level.  But we also experience these emotions at a far greater level.  When someone feels thankful to be alive, who are they thanking?  When someone despairs at possibility of life's meaninglessness, where is the emotion directed towards?  These sorts of emotions are data that require explanation.  Reductive accounts appealing to evolutionary mechanisms seem unsatisfying to me.  So, absent other candidates, the best explanation seems to be that sorts of emotions come from a part of human beings that isn't formed by physical mechanisms.
