I don't see why you find it difficult to see the cause and effect in evolution. Although it is not always explicitly stated, it's obvious that the theory in simple terms says that change over time in genetic variation (effect) is caused my various mechanisms like natural selection.
If you have a problem with the semantics of the phrase "natural selection" so be it. I don't. I can see that 'selection' may imply a conscience decision, but as defined in the theory, it clearly isn't. The 'decision' in this case is made by natural processes without a specific goal in mind. Hence
natural selection.
The terms conscious and unconscious or automatic selection as in the link you provided is different in the sense that these are decisions made by people through their actions of breeding or planting animals or plants. These decisions may be with a specific goal in mind. The variations that are selected by people to plant or breed again is not necessarily the fittest to survive anymore as in natural selection, but are selected for other characteristics that might be beneficial to those people.
Could you please be more specific to which article you referred to at cosmicfingerprints.com. It looks like you have to subscribe to some mailing list.
But at first glance, it looks like the site is full of flawed arguments...
Kenneth Miller on a Youtube video said that Natural Selection is "blind". But why is Natural Selection never "stupid"?
Stupid implies intelligence (or the lack thereof) with some goal in mind.
