There is no observable evidence for a reproducing living cell being created by purely natural forces. If you think I'm wrong, then please name it.
I was not talking about a living cell, I was talking about biological molecules: amino acids, purines, pyrimidines. We observe these molecules forming naturally. We do not observe any of these molecules being created by any deity.
There is actually a law, called the law of biogenesis that says life comes from life.
So what living meta-God gave rise to the Abrahamic God? You need to think more carefully about that 'law', which has been shown wrong since the late 19th century.
Nobody was there, so what can we do?
Look at the remaining evidence. Can the police only solve a crime if there are eye-witnesses?
Would you accept any sort of evidence of design based on complex specified information being created? We see new complex and specified information being introduced by intentional design all the time. Any examples that natural, inorganic molecules produce specified complex information?
ID proponents need to test their claimed design detection methods; to date I have not seen any of their methods being tested. I am aware that Professor Behe has accepted that his Irreducible Complexity idea is not impossible for evolution, though it is more difficult for IC systems to evolve than for non-IC systems.
For the other proposed design detection methods, there needs to be rigorous testing to ensure that they work as intended. I know that, as Dr. Dembski pointed out, that a false negative is always possible; Something may be designed to give the appearance of non-design, but actually be designed. Some parts of cryptography, for instance, are deliberately designed to appear random, while not actually being random.
It is more important to test the accuracy of positive results for design. Something like a thorough double-blind test would be needed.
I will not accept results from an untested claimed 'design test' since any such results would be too prone to error.
I will also not accept the results of raw, oversimplified probability calculations. Such calculations often omit crucial elements, such as the effects of chemistry, or else make unwarranted assumptions. Any such calculations will need to specify all assumptions made so they can be checked.
