Hey @Irenus, I appreciate you sharing that.
Of course many people think of the Bible as science for stupid people - particularly when it's reduced to its more fundamentalist manifestations. Those fundamentalists who say that the Bible is literally true have shot themselves in the foot already. By default, they are history deniers and have doomed themselves to subscribe to a rudimentary world knowledge before the emergence of science several thousand years later.
However, rather than completely writing off the Bible as merely pre-rational superstition, I give it credit for when it was written with the limited information humans had at that time. These are ancient ideas (the story of Genesis was not a new one and has been around for over 10,000 years) that were created with so much blood and effort that it's incalculable.
For one thing, I don't think it's an accident that the axiomatic Western individual is someone who was unfairly nailed to a cross and tortured. Even the ancient civilizations understood that in order to rise, we must pick up our own suffering and bear it. Like the story of Christ (and unlike our animal ancestors), we should be conscious about others in the process to help move society and, by extension, humanity forward. It's clear that those responsible for propagating such mythological accounts understood that human beings need to make sacrifices in order to progress.
We see this acted out to begin with in the Old Testament where the people made genuine archaic sacrifices. They would take something that they believed had value (often a prized animal) and burned it as an offering to God. That's not as stupid as it sounds. Consider the reason it was burned. As far as I've been able to tell, is because of the ancient perception of the world (a flat disc with the sky acting as bowl on top. Beyond that bowl was where the gods existed). That grand sense of awe a secular person feels when gazing up into the infinitesimal sky was interpreted by these civilizations as something divine. What else were they to think? So if they burned something and offered it up to a deity, the smoke would rise and God would be able detect the quality of their sacrifices.
I see that as a dramatic representation of the fundamental idea that sometimes, in order to make things go well in your life, you have to let go of something that you love dearly, or of something you deeply want to do. Consider the sacrifice of waking up. Many of us have let something valuable go (a belief system, often including family) in hopes for a better future - either for ourselves or for others (our children).
To get to the heart of it - what's the most valuable thing to each and every one of us? Our lives. And that's the central injunction of the mythological figure behind Christianity... someone who voluntarily sacrifices their life for the benevolent will that mankind has a better future. For one of the earliest attempts at surmising the meaning of life, that's not bad at all, if you ask me. But to weaponize these accounts as literal and a means for control through organized religion - that's when the symbols you speak of get muddied, ridiculed and demonized, be it by disenchanted individuals, or entire intellectual movements.
