The Problem with Christians

[Cyberman]

You are confusing a constant conjunction for a principle that denotes a causal relationship. If there is some reason life comes only from life, you might have a candidate for a natural law, but as yet you have nothing but their constant conjunction. If life did arise from non-life, then the conjunction isn't even constant. But you are declaring that the conjunction is constant, so you are declaring that life never came from non-life, and that is begging the question. Whether life ever arises from non-life is an empirical question which we simply have not answered yet. An indeterminate correlation is not a law.

"unless you can give an example of non-life producing life."
Whether I can give such an example is a moot point, as what is necessary to disprove the principle is not that any one person can give a counter-example, but that one is in principle possible. You keep stumbling over this point, which leads me to believe you don't understand the philosophy behind science much at all, or, that you are being purposely thick.

It's worse than that, as it happens. Fiat declaring that non-life can never produce life is both shutting out likely evidence to the contrary and shutting down investigation into the posslibilty whatsoever.

Viva the creation scientific method!
