Project Summary: One of the greatest mysteries of all times is how life originated on Planet Earth. Did it come from space, or did it appear spontaneously here on Earth? Even the most basic and primitive cells are incredibly sophisticated and complex mini-universes that defy explanation as to how they formed. Life is truly a miracle. Investigate about the origin of life on Earth and write an essay about it. The essay must be at least two paragraphs long, and each paragraph must contain at least five sentences (you can write more than two paragraphs and more than five sentences per paragraph if you wish to do so).
