THE BEST INVENTION? DIFFICULT TO SAY !!!

       Difficult choice (By R.F. )

There are many important inventions and discoveries throughout history. 

However, it is hard to choose which is the best one.

One of the first discoveries was the fire 1,6 million years ago.  It was very

useful due to the fact that primitive humans achieved to cook the food

and to protect from cold and wild animals.  In my opinion, it was a great step

for Humanity. Alexander Fleming discovered Penicillin in 1928 and so,

millions of lives were saved. Nowadays, this one is still used. Besides,

there are many inventions that have helped to improve people's lives

such as, the Wheel in 3500 a.c., the light bulb by Thomas Edison in 1987,

the phone by Antonio Meucci in 1854, the automobile by Carl Benz in 1886,

the mop by Manuel Jalon Corominas in 1964 and many more.

In short, every country should support research to improve people's lives.

Currently, everyone is waiting for the discovery of an effective vaccine

against coronavirus, so we could have a life like before.  Therefore,

in my point of view, it is the best discovery.
