Should Tyler Cowen Believe in God?

A little while ago the prolific and intellectually-promiscuous Tyler Cowen solicited the strongest arguments for the existence of God, and then with some prodding followed up with a post outlining some of his reasons for not being a believer. I can't match Cowen's distinctive mix of depth and pith, but I thought I'd take the liberty of responding to some of his reasons in a dialogic style, with my responses edited in between some of his thoughts. Nothing in here should be construed as an attempt to make the Best Argument for God, and the results are rather long and probably extremely self-indulgent, so consider yourself forewarned. But here goes.
