he Internet. This is partly for selfish reasons - he internet has taught me morethan anyone or anything else - for that reason it is the most important invention that has an effect on my life. What is the greatest invention in your opinion and why?

The greatest invention of human beings is probably the electricity. Without it,I think,the darkness will become the part and parcel of our life. The invention of computers had become impossible without it.
