Is the origin of life unique to Earth, or has it happened many times before on other planets and moons of the Solar System and the universe?

Assignment #3:One of the greatest mysteries of all time 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 on other planets and moons of the Solar System and the universe? Did life start with RNA or DNA, or none of them? Did meteors carry 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? What do we call “life”? Is a virus alive, for example? Did life start with cells, or did it start with molecules? If formed on this planet, what ingredients were needed to form it? Did it form in one year, a thousand years, or a million years? How exactly? If we would like to form life in an Earth Science lab, would we be able to do it? How can the origin of life be so mysterious when it is all around Earth?Investigate about the origin of life on Earth and write an essay about it.
