Here's a fascinating video which shows the incredible, breath-taking complexity of the chemical machinery of every living cell. What is being shown is very arcane and really doesn't matter (Those who wish to read more about it can find an explanation here).
Just watch the video and marvel at how wondrous it is that the Crea ... oops, I mean blind, unguided processes operating solely by chance - orchestrated the construction of such an amazing organization of molecular machines which, once in place, are capable of carrying on these processes completely autonomously without any intelligent input.
To be sure, it takes faith to believe that there's an intelligent mind responsible for the universe and for life, but it takes, in my view, a superhuman effort of the will to believe that something like what's depicted on this video could have all come about through random chance and the laws of chemistry. One has to simply not want to believe that there is a Mind behind it all in order to come to the conclusion that there isn't.
There are some religious believers who hold that we should have faith regardless of what our reason says, regardless of what the evidence is. This view is called fideism. Fideists maintain that when they encounter difficult evidence or experience doubt they should just believe and not waver. Naturalism, the belief that natural processes and forces can account for all the phenomena we observe in the universe, is, in my opinion, a kind of fideism.
Everywhere the naturalist looks he sees evidence of intelligent design, but, scrunching up his will, he repeats ten times, "Nature can do it."
He has no evidence of this, however. He's never seen nature create a cell nor create the information needed to operate a cell, even though everyday he sees minds perform such amazing feats.
Even so, his faith that there exists no Mind capable of creating universes is so great that he's impervious to the lack of evidence and the existence of contrary evidence. He's a fideist of the the first order.
