Pleaaseee heeelp <br>explain the origin of the universe precedes the origin of life
Nastasia [14]
The origin of life depends on a wide number of issues, all related to the existence of planetary and stellar bodies, chemical elements and the favorability of conditions for life created with such elements and under conditions not overly chaotic or disruptive and with energy sources that are balanced and moderate. As a result, the conditions for life can only result after the conditions of the universe are settled. It took the universe approximately 9.3 billion years to form galaxies and stars and planets that satisfy the demands of life on a fundamental level. It then took 4.5 billion years to condition the Earth through inorganic and organism progression to achieve the pinnacle of creation, which is humans.
