"Natural selection" is science's substitute for "God did it". "Selection" requires what? A choice.....no? How does a creature mutate genetically and then 'select' which traits it will pass on?
There you go, you are showing your ignorance.
Everything "genetics" are passed on through reproduction, it is not conscious choice by made by God, Designer or spirit.
Let's just focus on hypothetical example or scenario, just on genetic between parents and immediate offspring without the very long process of natural selection evolution:
I am sure you have seen video about the animal kingdom, where you see two or more male creatures contesting each other for rights to mate with a female or group of female creatures. It is to see which one of the contestants is "alpha".
Sometimes is about strength, which could mean violent clash (fighting), but that's not alway the case.
Sometimes such contests are about their looks (eg which has brightest hide, fur or feathers), or the ways one move (eg the ability to dance), or the voice (eg some birds are known to contest each others, by it singing).
There could be any number of reasons, in what ways it is chosen and which male contestant wins. Not all contests involve who is the strongest.
So the winner of contest, get to mate with a single female or with a number of females. And whatever partnership involved with the matings, the offspring will inherit traits genetically.
Now here are some questions for to answer:
Does God factor to any of this (above) example that I have given you?
Did God choose who is the winner?
Or is it all selected by the winner and female(s) that witness the contest?
In such a video, I see everything goes through genetics, via reproduction, hence by nature, not by chosen by a supreme divine being that you called God.
You keep showing images of animals with many different colours, eg birds, frogs, fishes, etc, but what I see is just "nature", all natural and all genetic, with no God involved in the ways they all look in those photos.
Lastly, in every science and in every technology, I see it is done through human understanding, human creativity in finding applicable solutions, human experiences (eg trial-and-error (testing, and developing prototypes), hard works, etc).
It is not just evolution that don't involve God, every other branches and fields don't involve god, eg physics, astronomy, chemistry, geology, any field of engineering, electronics, etc. None of these involved "God did it".
Any answer that involved "God did it" is nothing more than lazy cop-out, ignorance, blind faith and superstition.
Saying "God did it" isn't science, and it isn't testable, observable or measurable explanation.
So why single out evolutionary biology to be the only one that don't involve "God did it", when every other science don't god for anything?
You mention "colour theory". Nothing in colour theory involved "God did it". Does this theory, ever mention "God"?
I find whenever you claim that scientists are committing vast conspiracy against god and religion, to be absurd, biased and worse of all, dishonest.
And you should look yourself in mirror. The person who's being a conspiracy theorist, is you.
