Evolution of life..

"How did we get here?" And" how did mankind come to exist?" It has always been a mystery. For so long astronomers, philosophers, and even mathematicians and many other have come up with different explanations. My opinion about the creation and evolution is different. It is estimated that our universe is created 10 billion years ago and the creation of the earth took place around 4 billion years ago.the first living organism to appear was the cell and develop into a living creature.
