Something truly fascinating to consider! :)
All living things consist of a precise sequence, arangement, flow of energy and a particular chemistry from non-living things to take a particular form as a "living thing".
It is amazing that we now understand that we are in fact a well timed/placed combination of non living things over vast periods of time that have come together through various processes and reactions in just the right way to become the living, breathing, aware and intelligent beings we have evolved in to today.
Consider for a moment, ionic bonding, the platonic solids and the elements..
Electrons, protons and atom nuclei, the very same thing that energizes and stimulates the sun and the stars is the very same things that energize and stimulate our brains neuron cells and nerve receptors, this in turn gives us the ability to think, feel and become perceptive.
One has to truly consider the credibility that there has always been a degree of awareness or even simple thought on an energetic level via one form or another trying to branch out in to new possibilities and outcomes through the cosmos long before life on earth.
If this was not the case, then we truly are not "living things" in context, but rather a bi-product of the reactions created by combinations of non-living things perceiving an illusion that we are alive.
To simply imply that everything is just a random mistake or "happens just because it happens" is an evasive statement without foundation to deem suitable as a scientific solution. Science does not accept "mistakes".
Natural selection would require some external force in any given shape or form to actually "select" for that particular theory to hold plausible. To select requires the act of thought, decision and intention to make a "selection".
It is not natural selection that takes place, in fact, it is the probability relative to mathematical value that rule out the former.
Geometry, ratio, sequence and mathematical order are intelligent structures that do not allow for mistakes.. It is people who make mistakes. ;)
Love you all! <3 xxx
