In nowadays, where life is surrounded with numerous sciences, people are beginning to lose the wisdom of the expertise their ancestors have gained in life experiences, and may even find those wisdoms silly or somewhat “useless in life.” Yet, we do not realize that a lot of knowledge we learn in school or find in textbooks is the gifts our ancestors left for us----their wisdom, their expertise.
Thousands of years ago when science isn’t available, people already had the knowledge of astronomy and forecasting by interacting with nature. By examining the celestial bodies, searching for signs of any disasters such as droughts, and take preventive measures to avoid the damages and destruction, our ancestors were able to maintain a wealthy life.
Expertise is gained through life by our ancestors years ago and the aboriginals today all use the same wisdom they learnt from nature and the environment they live in. Different places have different local indigenous, and they all have different stories or wisdom behind them.
So no matter how other local expertise are, we should not look at them with unfriendly eyes, but treat them as a wonderful and special wisdom.
