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.
The best invention would be electricity. Electricity was the reason why human life started to progress. Technology, innovations, inventions was made and improved since electricity was invented or discovered. It made our daily lives convenient and easier. It's difficult to survive each day without electricity.
I think that I am agree with you,it did the life a little more comfortable for most people allowing a quite broad development thanks to the applications that were created from this to the present day,but more than an invention was a discovery I think,and before that was perhaps the language to communicate with each other, the discovery of fire have also been basic to human history,In fact there have been many but I only named a few.
