One of the things that dramatically impacted me when I was an agnostic was the sheer complexity of the cell that's beyond imagination. You can almost think of a cell's complexity as being similar to a large city like Istanbul; all the kinds of activity happening in a city like Istanbul and that same type of molecular activities happening in the cell. And I just don't see how anybody could reasonably think that something as complex as a cell simply emerged to unguided undirected processes. It looks to me as if there really has to be a mind to explain where life comes from at its basic level.
