What was it like when life first became possible?

The cosmic story that unfolded following the Big Bang is ubiquitous no matter where you are. The formation of atomic nuclei, atoms, stars, galaxies, planets, complex molecules, and eventually life is a part of the shared history of everyone and everything in the Universe. Even though all of these things likely arise at somewhat different times at different locations in the Universe, largely dependent on the initial conditions such as temperature and density, once enough time goes by, they’re found literally everywhere. At least once, here on Earth, life began at some point in the Universe. At the absolute latest, it appeared only a few hundred million years after our planet was first formed. That puts life as we know it arising, at the absolute latest, nearly 10 billion years after the Big Bang. When the Big Bang first occurred, life was impossible. In fact, the Universe couldn’t have formed life from the very first moments; both the conditions and the ingredients were all wrong. But that doesn’t mean it took all those billions and billions of years of cosmic evolution to make life possible.  <a href="https://medium.com/starts-with-a-bang/what-was-it-like-when-life-first-became-possible-593aef3c8a52">Visit Now</a>
