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'.
The problem with your kind of thinking about the age of the earth and universe is, there is all kinds of evidence that the universe is much shorter. Some of the evidence points at 10,000 years. Since you can do Internet searches that show this, and since you can get deeper by studying the young-earth evidence with those who explain it, believing in a old-universe view is a choice... not reality of an old-universe.
In other words, whatever looks good, and however you want to apply the evidence, is like making a choice to believe whatever you want.
The only way to know how old the universe is, is to believe the witnesses who were there, and recorded their witnessing.
The first two chapters of the Bible were witness records copied by Moses from text in Egyptian libraries about 3,500 years ago. These texts probably have crumbled away with age long ago. But they might still be hidden in some lost Egytian library somewhere... hidden under the desert sands of Egypt.
You can't apply today's evidence without knowing the past parameters that the evidence needs to be applied by. Maybe they are applying the evidence in a wrong way. We won't know until we have witnesses or a time viewer/machine.
