How life originated on Planet Earth

One of the greatest mysteries of all times is how life originated on Planet Earth. Even the most basic and primitive cells are incredibly sophisticated and complex mini-universes that defy explanation as to how they formed. Did life come from space, or did it appear spontaneously here on Earth? Is the origin of life unique to Earth, or has it happened many times before in other planets and moons of the Solar System and the universe? Did life started with RNA or DNA, or none of them? Did meteors carried life to Earth? Was Earth different than it is today when life started on this planet? Did life appear when there was no water on Earth? Life is truly a miracle. Investigate about this topic and write an essay about it. The essay must be written entirely in your OWN words. The essay must be at least three paragraphs long, and each paragraph must contain at least five sentences (you can write more than three paragraphs and more than five sentences per paragraph if you wish to do so). If needed, you can quote, but this does not count towards the last tally of number of paragraphs and sentences being required from your OWN writing. Use citations in parenthesis, APA style, if you paraphrase information from other authors (note: paraphrasing is not copying and changing a few words from other authors’ writings, it is writing it in your OWN words to explain other authors’ writings). Also, in your assignment use at least three references to investigate about this topic; use APA style and list your three references at the end of your essay
