Benjamin was very smart.He was not afraid to experiment. When a thought popped in his head, like lightning is a source of electricity, he had the determination to prove it.
Ben and three of his friends were trying to analyze electricity and experiment with it. Two of his friends got electrocuted while they were working on this. While they did this experiment, they obviously proved that lightning was electricity. Yet, the world had not seen it, so Franklin decided to do the kite experiment, but alone.
Ben would always think about what he wanted to do in the experiment, find the materials, and think of how he could fix something if it did not work. Finally, he would gather the materials and do the experiment. Sometimes this process took a while. Ben was very keen to show the world that lightning was electricity. He wanted to prove this. He decided to use a metal key to do this experiment. Yet, he still needed a way to keep the key in the air. In 1752, on a stormy day, he raised his kite with a key tied near his hand. He could feel the electric shock go through his body. Ben had finally proven and understood lightning/electricity. Later that year, he invented the lightning rod.
In 1740, electricity was a novel and fashionable subject. Most people thought that electricity was as mysterious as heaven. When Franklin gave the idea of lightning being a source of electricity, people were exited, and he was supported all around the world.

If Ben hadn't discovered lightning was electricity, we would not have anything that could run on it. Although many people have researched electricity and found how it worked, fewer research and experiments would have happened. Electricity has gone far from Benjamin Franklin's basic idea. We now have computers, lamps, speakers, T.V., and many more things that run on electricity.
