torridon,
Ideas such as random variations, chance, emergent property etc. are not explanations.
They are part of the explanatory backdrop: for example many of the established statistical tests involve estimating the risk of chance, where findings are deemed to be 'significant' only where the risk of chance is estimated as being no greater than a certain value (usually 5%).
They are attempts to keep possible non material explanations at bay and to circumvent all such ideas.
We've yet to see any non-material explanations, given the absence of an underlying method to give context to claims of the non-natural: we do see plenty of fallacies in support of the non-natural, which is telling.
It is a fear of the non material. The God phobia!
Nope: it's impossible to be fearful of claims there is no credible evidence for.
What I am attempting is only to explain Consciousness, Self, Life and other phenomena that we experience everyday. For this, taking a cue from the way man made objects get created and how they evolve, is perfectly in order. As above so below!
Which is your personal incredulity kicking in again: you are also using the fallacy of equivocation here too, since you are using 'evolve' differently by using the same term to refer to both the design and refinement of something manufactured (such as would be evident in patent documentation) with the unguided biological process of evolution (as per the TofE).
