Thank you for your question.

This looks like an essay topic to me. I would write about the impact of chemistry on industries such as plastics, pharmaceuticals and mrtals, the impact of pharmaceuticals on world health, the impact of weapons such as explosives and in ancient history the impact of new forms of working metal ie the stone age, bronze age and iron age.

I have attached sources for your reference.

It is thought that perhaps chemical reactions having to do with atmospheric collisions of hydrogen and oxygen and salt, ( NaCl) were what drew water onto the earth which made the environment suitable for life.

Chemical reactions in the watery soup then formed life on Earth. I happen to believe God was in control of all this as it is too great of circumstancial coincidences to just ‘happen’.

Cavemen used the chemical reaction of heat to make the first fires.

Basic chemical reactions, once observed, understood, and controlled, were used in the very beginning of medicine to treat the sick and injured.

Chemistry was used early on to forge metals to create golden statues and body armor/swords for using in political influence and wars.

Chemistry was used to flavor foods with spices….and were a big reason people traveled…..to ship spices from far away to season food for Royalty ….causing the far reaches of the world to be explored in search of rare and delicate spices.

These are just a few….there are many many more.
