Speculations about alchemy

People used to call anyone who was able to make a breakthrough in any field of science as a sorcerer and it was labeled as an evil thing or a demonic process. Maybe “sorcerers” were actually scientists but people were too ignorant so they called them sorcerers instead of calling them smart. Maybe this kind of knowledge was preserved and only certain people were allowed access as knowledge is power and may be dangerous in the wrong hands, a modern example of this is Noble’s dynamite which was invented to benefit people and make mining for minerals easier and then was used in warfare to kill people.
