6. How Life Came To Be
- Includes: Evolution & The Big Bang Theory
While some battle against both Evolution and the Big Bang Theory, science actually backs both completely. In 1927, Georges Lemaître was the first to note that the expanding universe could be traced back to an originating point, which he actually called the “primeval atom.” We now simply call it the Big Bang Theory. In 1929, Edwin Hubble then found after much analysis that galactic redshifts are drifting from one another, which confirmed an expanding universe.
Finally, in 1964, the Cosmic Microwave Background was discovered and, along with more physics discoveries, pretty much confirmed the universe started with a bang. Yet it was Charles Darwin & Alfred Russel Wallace who proposed natural selection and the theory of evolution. This dictated that only the strong survived and thus, each species developed key traits to do so over several generations. This included how humans eventually evolved into what we are today. Both were insanely crucial scientific breakthroughs.
