And where would the scientific advancement stop? Intentionally or unintentionally, good or evil intentions, the further we become seperated from the natural order of things, the more man loses his vision.
Often what we think of as "advancement" is actually at a cost of other animals on the planet; this is because we as humans think that we are the most important creatures on the planet. If anything, we are far too advanced already, as humans rule every corner of the earth.
E.g the invention of the bus, just to give one example. On the surface one thinks "It gives us much more comfort, allows us to travel longer distances, etc, let us reach previously unreached places".
Well actually, it is one more step away from our lives as they were designed by JAH to be. Before people could travel such large distances, they would be forced to look into their community, to LIVE WHERE THEY ARE. Creates a very un natural environment.
However far humans think that they going "up", they must eventually come "down", back to the earth, at which point they will find themselves. Humans are already far, far "up" on other animals. If we lived as Jah designed, we would know ourselves and we would not rule the earth to the extent that we do,
You gave the example that we now know that the apple seed is poisonous, and the example of bush doctors being a science. Does it not occur to you that almost every other animal on this planet manages to maintain a healthy population without all of this research? This is because they live in the environment which jah naturally created for them, and everything is kept natural. They have never really went in to deep research about WHY it works, all they know is that it WORKS, and so they can live in hapiness
All the best,
