Now please describe a test, and a potential outcome thereof, that can conclusively demonstrate that your hypothesis of life is wrong.

Answer: his hypothes is falsified when the dirt in his backyard becomes a penguin.

But what O what will ever lend support to his "never" premise? Especially if he wants to rule out abiogenesis spread over 300-500K years as mainstream science hypothesizes.

Of course why bother making an honest reply VadeRetro? You accuse of straw man arguments then come up with this?

"his hypothes is falsified when the dirt in his backyard becomes a penguin."

No one expects a penguin to "poof" out of a hole in the ground. Since you were arguing in support of abiogenesis, you ought to be able to come up with a more likely scenario that is observable.

All you need is one living cell whose existence is not owed to reproduction, replication or human assembly.

Is that a big task? Maybe. But more reasonable than a magically appearing penguin.
