When people are asked about the most important discoveries or inventions made in the last two hundred years they usually mention something very obvious like the computer or the cell phone But there are thousands of other discoveries or inventions that hav

I firmly believe that man-made satellites are the most important inventions made in the recent 200 years because these satellites support mainly every kind of transportation and sometimes saves your life. For example, last year I was on vacation with my family and unfortunately, I lost track of where they went. Thankfully, I was able to have access to my navigation app and eventually found the way back. If man-made satellites don’t exist in this case, I will be completely lost and left clueless into the unknown. Moreover, if the satellites don’t exist, me and my family won’t even be able to go on vacation because without satellites the navigation on airplanes don’t even exist! Therefore, I believe that man-made satellites are the most discoveries made in the last 200 years.
