Whether you struggle with the great universe or how life has appeared on Earth, our existence multiplies with a bizarre turning of nature that we can not explain or understand. These questions can disturb us and feed us for our entire lives – but they are also a key part of human experience. Our planet is full of trees, herbs, birds, and bees. It also has a lot of bacteria. Everything is life and they all reproduce to preserve their lives.
But how did life begin in the world? How has a mass of cells moved from an inert collection of organic molecules into a being that is sometimes even intelligent?
The short answer is: we do not know exactly how life has appeared. There is a chance that, 4 billion years ago, aliens escaped a few microbes and let it run wild. And of course, many religions have supernatural explanations for the origins of life. Many scientists believe that life is a natural progression for planets containing the ingredients required for biologies, such as carbon, hydrogen, oxygen and other fundamental blocks. With the right spark – say, a flash of lightning – these foundation stones slowly develop into cell walls and DNA that are suited for reproducible life. Researchers continue to perform such experiments in laboratories, hoping to discover the formula to make life.
