Here’s a new take on how life arouse from non-life, a theory known as abiogenesis.
We know life exists, and it must have begun at some point in time. A new study combines biological and cosmological models. Professor Tomonori Totani from the Department of Astronomy looked at how life's building blocks could spontaneously form in the universe—a process known as abiogenesis.
He points out that the thing to watch is ribonucleic acid, or RNA, which is simpler than DNA that defines how we are put together.
“RNA is a polymer, meaning it is made of chemical chains, in this case known as nucleotides. Researchers in this field have reason to believe that RNA no less than 40 to 100 nucleotides long is necessary for the self-replicating behaviour required for life to exist. Given sufficient time, nucleotides can spontaneously connect to form RNA given the right chemical conditions”
He also brings up cosmic inflation, that some scientist have called a totally bonkers idea. He says that "it's calculated that thanks to rapid inflation, the universe may contain more than 1 googol (10100) stars, and if this is the case then more complex, life-sustaining RNA structures are more than just probable, they're practically inevitable."
So in his view, that is how life began, without God, who breathes life whenever it is needed.
