OK, this is your thesis and interpretation, and we can discuss that as long as you do not continue to misrepresent Popper.
I do believe you need to put the use of 'myth' in the context of analogy.
The original idea I wanted to discuss concerns two ways of interpreting raw observations come to us through our empirical means of discerning the world. For instance, when we see the sun rising in the East and setting in the West it appears, at first, and second glance, as though the sun is revolving around the earth rather than vice versa.
Add to that that the moon appears pretty much like the sun in its revolutions around the earth; and that during a solar eclipse we see that the moon and the sun appear to be the same size. These natural observations could be said to be lying to us. And in the most egregious manner since the design of the sun and the moon, and the way they look to the naked eye, make anyone speaking the truth of the matter (concerning for instance the size of the sun versus the moon) look perfectly demonic; or like a lunatic. Which is how many of the early scientists were looked at and treated. Many were burned at the stake.
What's important to what I wanted to discuss is the fact that both the scientist and the religious priest (the latter being the guardian of the communal myth) share the same basic empirical observations such that understanding how the scientist comes to a deeper perception of the truth of the matter is something of legitimate value.
What Popper reveals that's of immense value in all this is the fact that the pre-existing myth is itself a form of science. The ancient myth doesn't just accept observations at face-value (like a mere animal might). The ancient myth tries to make sense of the observations by, for instance, claiming the thunderstorm implies Zeus is angry.
Now it may seem childish to us to imagine equating a thunderstorm with an angry Zeus, and it might seem outrageous to call it "science," but what I wanted to discuss early on was the fact that even this seemingly childish equating of a thunderstorm with Zeus possesses the germ of modern science since the thunderstorm is being judged, evaluated, as a sign of anger, not happiness. The ancients could have seemingly said a thunderstorm means Zeus is happy. But that wouldn't fit into the archetypes of say "darkness" being bad, "coldness" being bad, "light" being good, "warmth" being good.
Ancient myths uses stories of an angry Zeus to say, for instance, that dark clouds, and cold rain, are archetypal synonyms for "anger" which, "anger," is thus itself being thrown into a particular bag of archetypes. By saying a thunderstorm represents anger, anger is being defined as a synonym for darkness, and coldness, even disorder, like the stormy sea during a thunderstorm.
Once we define light as good, cold as bad, disorder as bad, order as good, we're beginning to attempt to order our observations in a manner that will allow us to take some control over our world precisely by ordering it.
For instance, we can see the difference between downtown Manhattan, versus an aboriginal town built of mud and straw bricks. We can see the difference between a space shuttle shuttling men around the planet, versus an aboriginal witch-doctor with birds wings flapping as he runs from one shanty-town to the next to deliver his snake oil.
The differences above are related to a belief that the world can be ordered and understood using human logic and insight versus a belief that there isn't really any pre-existing design or order such that we should just take things as they are. The aboriginal witch-doctor doesn't know or care really if the sun revolves around the earth or vice versa. This lack of care is exponentially more natural, than the unique idea that the cosmos is "designed," and "ordered," in a manner requiring a God.
Which segues into why theology, and religious myth, are the seminal beginning of modern science in that they posit a design and order of such magnitude that not only does it require a super-intellect, a god, but because this god is a designer of great and profound order, we need but search out that order in order to order our lives in a manner that leads to say Manhattan versus bum fuch abo-land.
Agnostic thinkers often think science is virgin born. They don't accept it as a form of theology. And yet most good historians of science, to include Popper and Einstein, are clear as day that not only does modern science grow as a branch of mythological theology, but it is itself a form of what it grows out of. It is not virgin born. And thus it cannot redeem itself from the flaws of the mythological thinking that is part and parcel of what it is.
