What is the modern creation story?

In asking about a "modern creation story", the question seems to seek the scientific explanation that is an alternative to the many religious creation stories that developed in times past.
Scientist believe that the universe began with a cosmic event known as the "Big Bang" around 13 billion years ago. Eventually stars formed out of the cosmic material formed by the Big Bang", and our sun is a relatively young star. The Earth is a planet revolving around the sun, and was formed about 4.54 billion years ago.
When the Earth had cooled sufficiently, it was a perfect environment for the development of complex organic molecules. Some say that these conditions allowed certain molecules to self-replicate, which is normally something that only living things can do. Eventually, primitive living cells formed. And over the billions of years, these cells evolved into multi-cell organisms that were the forerunners of today's living creatures.
