What do you think is the best invention/discovery of the world.
How that invention/discovery is helping humanity ??
One example is Wheel/Tyre that made travel very easy.
In my own perspective, I think the best invention is medicines. Think about it many people would have died from illness and diseases just because of a cold or any other minor illness because there is no medicine. Medicine is the reason majority of humans in our society today is still alive and healthy. Medicine is the most helpful invention humans ever made
