But then you are only offering a “just-so-story” spun from imagination. Many equally valid “just-so-stories” are spun by others to explain the same phenomena – the reason that philosophy today is just a series of arguments between opposing “just-so-stories”.
You also don’t seem to understand what science is. Science is a methodology, not a series of statements to be believed as truth. The methodology weeds out subjectivity leaving only demonstrateable objective relationships. Of course, during the process of reaching an understanding of these objective relationships requires wading through a sea of guesses as to the nature of those relationships to eliminate those with incorrect assumptions that fail the objective testing. I guess you could say that this methodology is just a psychic meme but it does work to reach an understanding reality well enough to give us the technological world we live in today.
I have no argument against science or empiricism and their usefulness.
It has less to do with explanations of phenomena and more to do with the "psychological primacy" of our experience. For example, when I am talking to somebody my cognitive functions remove entire strata from the objective reality of the person. Rationally I know that they shit, have body odours, are perhaps digesting some food and so on but that doesn't enter the "image" I'm dealing with, it's hidden or abstracted from my cognition (unless I intentionally explore the idea). In fact, in order for it to be "real" in the sense of efficacy, for it to have the desired effect in the world, the "image"
cannot be the objective reality of the person.
You can take this a step further and see a whole new strata of psychic reality. Does the average modern Western Christians really believe in God? I would argue that the large majority in fact do not. Because the reality of their behaviour (dictated by their unconscious position) contradicts their conscious ("Lacanian symbolic" or "spoken") position. Much in the same way that there is an objective reality that is abstracted, repressed, denied in my above example, the conscious position, the "image presented" is an abstraction from the reality where we see the average Western Christian obsessed with materialism is all it's forms - mass consumerism, ecological plundering, financial gain - all to do with this material existence and having very little to do with a fictional hereafter.
Ok, so why is this important? Because if we are going to have any idea of what the fuck we are actually doing and where we are going we are going to have to recognize this psychological primacy. Science is great but it's not going to solve our political problems, our inter-personal relationship issues, school shootings and so on. And what has this got to do with mythology? Well I would argue that mythology provides key insights to human behaviour, in some sense it's even "objective" in an abstracted form, in that it points to a reality.
Do gods exist? Yes of course they bloody exist. Why the hell are you here wasting your time arguing with Christians if you truly don't also believe they exist? You might argue that they exist merely as "fictions" in light of scientific materialism but there you would also be wrong. Does space-time exist in a significantly different way to gods? Here's my answer to that (read the first post):
