you think that the complex machines of nature that are far more complex than the ones intelligent mankind makes, are made by "blind unthinking evolution."
Yes. Evolution. The thing that often throws people is the timescale involved. The
evidence is that life on Earth started at least 3.7 billion years ago. And it has been subject to natural selection (plus countless random, mostly negative but occasionally positive) mutations since then. It's not as if, as someone stated on one of these threads 'man came out of a monkey's ass'.
