I just summarized the evidence that it is extremely unlikely.<quoted text>
Do you consider all things that science cannot replicate and that haven't been observed in the history of human record keeping unlikely? How about whale evolution from land mammals?
What evidence suggests that abiogenesis is highly or extremely unlikely?
The search for it has been exhaustive, with little to no results.
Whale evolution from land mammals may have occurred, but it did not occur in the pathway that Darwinists presently want us to accept.
In fact, that series is impossible by natural selection alone.
But it's good enough for the Darwinists anyway. It's a "just so" story. It just has to be so.
(both the whale series and abiogenesis)
