There is O (zero) evidence for abiogenesis.<quoted text>
Are you taking issue with the use of the word "possible," the modifier "very," or both?
It's possible because whatever cannot be shown to be impossible is possible.
The word "very" was chosen because there is evidence for abiogenesis, and none for divine creation, and evidence that the earth was bombarded with what would occasionally be earth melting, life sterilizing asteroids and comets, meaning that if the process were a natural one, it would likely have had to occurs repeatedly before it led to the permanent presence of life on earth. Let's look at the geological timeline:
The present chain of life seems to go back to when the earth was about a billion years old, meaning that no completely sterilizing event occurred after that date. The current estimate of the age of the earth is approximately 4.5-4.6 billion years. The late heavy bombardment (LHB) is thought to have occurred approximately 4.1-3.8 billion years ago. Our ancestral prokaryotic cells are thought to have first appeared 3.6 billion years ago. It seems likely that the process that led to these would have done the same thing several times in the hundreds of millions of years between the time when the earth and its oceans cooled sufficiently to sustain life, and the end of the late heavy bombardment, hence the word "very".
Despite centuries of searching for it, and trying to replicate it, science has been 100% unsuccessful.
No instance of it has been observed in all of history, not one, not once.
But you are free to take it on faith.
Abiogenesis is possible in the same sense as my shitting a grandfather clock.
