Answer:
Typed this out and changed the above's words a bit. :)
Step-by-step explanation:
The person I think is the most important is Albert Einstein. This is because he has made many inventions that changed the world and helped many people. He invented the light bulb and a type of heater for your home. He invented the light bulb so that people wouldn't need to carry around a candle to see in the dark anymore. The reason why I picked Albert Einstein is because if he didn't do that, we'd all still be walking around needing to carry a candle stick and we would have a hard time seeing everything all at once.
