Evolution does not explain origins
Meh, this is a semantic technicality. Where everything came from, including the bits and pieces that make up life (i.e. amino acids) and how those pieces work together in harmony to make life what it is today all comes down to the same issue; you cannot have ordered complexity by random chance.
There can be only two options; guided or random. It cannot be both because they are opposing concepts, like saying the light is both on and off at the same time. Trying to say that both are true at the same time is nonsense which defeats the purpose of even having such definitions to begin with. If you want to say that off can be on and on can be off both at the same time then the concepts lose their usefulness as any kind of rational description of what the reality of the situation actually is.
In the same way, random cannot be guided and guided cannot be random at the same time without rendering the practical meaning of each of those concepts moot.
natural selection is not random.
Absolutely it is. Both the mutation and the location of the organism are 100% random (otherwise you must explain what guides the mutation to mutate in the way it does and what guides the organism to be in a geographic location which is favorable to the mutation).
If a mutation is favorable based on the location, the organism will be more likely to survive long enough to produce offspring. If the mutation is not favorable according to location, then the organism will be less likely to survive. Organisms are selected to live just as they are selected to die. If a canine mutates a shorter, thinner coat of fur in a cold region, it will die young. If it mutates a thicker coat of fur, it will likely survive. There is no guidance or intent behind any of it; completely, 100% random chance.
"Natural selection" is a favorite talking point because you see it as some kind of "program" but invariably you deny any programmer which is inherently irrational. You cannot have a program without a programmer and this is the most common distortion which keeps the theory afloat; you must twist reality to suit the theory in order for it to have any meaning at all.
Because you really are created by an intelligent designer with a desire to crave meaning and purpose, you will inevitably seek out
some kind of purpose behind your existence. You are too proud to accept servitude to an intelligent designer, but you cannot accept that your existence is the result of completely random, dumb-luck chance, so you opt for a middle ground; an implied intelligent program with no programmer. It's utter foolishness.
