The above should be an entry into "Grimm's Fairy Tales". "Darwinian evolution" neither posits a deity nor denies it and, as a matter of fact, Darwin was a lay minister in the Anglican Church. It's only near the end of his life whereas he became more of an agnostic, which may have been been more of a reaction towards the status quo, anti-science Christian elements of so many during that day and age.
It is simply true that acceptance of natural selection theory would lead to depression, and by most accounts Darwin himself had depression.
The acceptance of subjectivity on an intellectual basis in the scientific community is very low as it is, and natural selection theory makes things very much worse.
How subjectivity works is that you reach a conclusion about what it is that chooses, by choosing the conclusion.
For example a hare is escaping from a fox, and has some options like run, skip, hop, turn, stand still, and attack. Supposing the hare chooses to hop.
Now the question is, what made the decision turn out hop instead of the other options run, skip, stand still and attack...?
There are by definition at least 2 correct answers to this question, because it is categorically a subjective issue. We might choose between "courage" and "recklessness", as what it is that made the decision turn out the way it did. How we arrive at the answer is by expressing our emotions with free will in relation to the decision, thus choosing it. The logical validity of the answer depends on that it is chosen. So if we would say it is "courage", but not choosing the answer "courage", but instead forcing the answer without the possibility of any other answer, then it would be a logical error.
The reason facts are excluded is because facts are obtained forced by evidence, resulting in a model of what is evidenced. All forced answers are excluded, because force is inconsistent with the freedom of the agency in a decision. If we say it is a fact that it is courage, or a fact that some electrochemistry made the decision turn out the way it did, we would be equally saying that a decision has the logic of being forced, because of the force required for facts, which a logical error of contradiction. The agency in a decision cannot be both free and forced at the same time.
That is basic understanding of subjectivity, and evolutionists do not have it, thereby taking great risks with their mental health.
Only creationism provides validation of both fact and opinion. Opinion applies to the issue of what it is that chooses, the creator, the spirit, the soul etc. , and fact applies to the creation, the resulting decision, the available options etc.
