I believe we can with absolute certainty (a rarity) state we are not the end products.
Yes, we can state it. We cannot eliminate the contigency we are in error in asserting the absolute.
Survival depends on making judgements. In the wild there is little/no time to Q & A endlessly allowing for other viewpoints. Survival often requires snap judgement. Seeing things in a constant state of black or white is survival oriented for animals.
Humanity has become socially accustomed to less urgent circumstances. Yet, the black and white absolute mindset is still there.
Personally, I am now only comfortable with expressing my ignorance of things in place of a lifelong tendency to assert mastery where there was only presupposition of my premises.
You see, we all tend to base our conclusions on our presuppositions no matter how careful we are.
When science has been most productive and effective it has used a methodology which tests conclusions against premises.
Even scientists fall victim to the desire to see their premises end in proofs positive. Whenever this happens the non-scientists gloat accordingly.
I don't know how completely accurate the model for evolution matches reality. I bring my own ignorance and presuppositions to any tentative ruling. As do we all.
If I emotionally need it to go one way or the other I'm sure it will.
Any of us not trained to act otherwise would do so too.
In the final analysis none of us here can do more than joust AS THOUGH we are debating facts. I think it is likely we are actually doing something less cut and dried. I think we are trading blows using presuppositions as clubs.
Let me give you a ragged analogy, if I may.
I watched a TV commercial the other day advertising HIGH DEFINITION TV.
I was watching on an ANALOG screen with an ordinary broadcast.
The commercial showed a HI-DEF TV with an image on it which was asserted to be HIGH DEFINITION and superior in every way to my own analog TV screen.
Now, I have to ask you----is it possible I can SEE the difference using my analog screen? Why, no!
I have to assume the High-Definition broadcast being depicted on my analog screen is superior in every way by relying entirely on anecdotal testimony by the announcer and the smiling faces of the people in the commercial.
Looking at the details of evolution, science, mathematics without a degree in those subjects is like watching a High-Definition TV commercial using an analog tv screen.
You can't really SEE the difference and you might not want to invest in a very expensive investment to test the veracity of the commercial's claims. You might just decide you are happy enough with what you already have.
I think a lot of people end up doing that when challenged by claims of something OTHER than what they already possess as "facts".
Belief is not proof.
They wouldn't call it belief it were proof.
Operating your mind without proof is like driving blindfolded. Occasionally you will bump into things that hurt.
