Dear @chbartist
We should not be too hesitant to accept this fact that our ancestors were more dependent on estimates because they did not have the means equipped with modern techniques as of today, due to which all their methods and knowledge are faulty and not approved by scientific method. Were. They rely on tests and errors. Though he had lack of scientific method and testing, in most cases his decisions proved to be correct because most of his experiments were based on experience. The cycle of time keeps running. Time changed, circumstances changed, technology changed and people also changed. The flaws were already there and the food is still there any person can never be perfect Yes we can definitely learn from mistakes and try to fulfill the shortcomings.
Thank you
