When biologists talk about the cell being a microscopic factory filled with tiny molecular machines they mean that quite literally as this brief video illustrates. The video doesn't explain what's going on, but it's all pretty amazing nonetheless:
Cells are far more complex than is shown here, but the first cell must have been at least this complex. How did such a thing ever arise through an unguided, blind process, especially before there were any reproducing cells for natural selection to act upon?
Faith is belief despite the lack of proof. Blind faith is belief despite the lack of evidence. There's no evidence that cells actually did arise through purely natural processes and good reason to think they didn't. So the belief that they did, the belief called naturalism, is an exercise of blind faith on the part of the naturalist, which is precisely what naturalists often criticize theists for. Pretty ironic.
