make are life more efficient and communicate more effectively in business, education and personal lives.

The internet is the 2nd best invention because without the computer the internet would not be possible. It does all the things above plus improves research, shopping, and entertainment.

The third most important invention was the car because it improved transportation and increased transportation of goods. Computers and internet move information a lot faster than a car.

The fourth most important invention was antibiotics. It made it possible for people to live closer together and have longer lives. I have not been personally impacted by the use of antibiotics so I only ranked it fourth.

The fifth most important invention was a plane. It made transportation of goods and people around the world possible. I still think a car is more important because it is used in our daily lives. Antibiotics are more important because we would not be able to travel the world without diseases from other countries.

I noticed that my order is from what I use the most to what I use the least.
