I provided just an example of this, with the Nylon bug.

This wasn't mine, but I think it's a warranted conclusion as your argument is very similar to Behe's demands in the Edge of Evolution.

This is not an attack on your character - it is a comment regarding reasonable belief. This is a comment directed specifically towards your level of proof you require. HOW on earth do you regard this as a personal attack??

This is a comment regarding epistemology. AGAIN, how on earth is this a personal attack???

I certainly don't - you are creating a strawman.

Nonsense. Not only has your burden been fulfilled (I provided the Nylon bug), but you are confusing a demand for certainty (a logical proof of God's existence) with science - which works from abduction/induction and thus is not *certain*. In short, you are confusing or obfuscating your epistemological standards.

No we don't, not for science. Seriously, what in science has been absolutely proven?

These things have not been 'proven' in the same sense you are requesting that evolution be proven. You are equivocating. We have good evidence that nuclear fusion happens, but the fact is, we are not certain. After all, we could all be brains in a jar that are being tampered with by a malevolent doctor.

Another point I could point out is that since we do not have an underlying theory of everything then you are necessarily missing a point in your equation. Therefore since you are missing this point, we should reject this evidence. This is akin to your rejection of evolution because we don't know the chemical pathways of all common descent.

Your personal feelings also led you to believe that most mutations were negative. Seems like your personal feelings are irrelevant. I provided you an example of a biochemical breakdown and you IGNORED it.
Were I to conclude anything from your posts it would be that you aren't interested in the actual evidence.

That's also not what I have been saying. Natural selection is not the only factor and fossils aren't the only evidence. You are cherry picking my quote here. You ignore the Nylon bug which provides you with exactly what you ask for and you ignore the twin nested heirarchy.

No, it's not - however this is not a question for the biological community. You are asking about abiogenesis and I gave a model (WHICH YOU IGNORED) on how it could have occurred.
I don't think you read the link, as it provides adequate evidence of what you are demanding.

How are you defining 'understand' and 'advanced' here - since the nylon bug is 'more advanced' by several criteria then it's predecessors (as it can digest nylon)!
You are being vague.

This is an assumption. You are assuming that the earliest single celled organisms had DNA. I have provided evidence for abiogenesis (you ignored it), but this is irrelevant since you are pushing back the goal posts FROM evolution to abiogenesis.
Abiogenesis could be totally false, yet the theory of evolution could be true - do you know why?

This is a strawman. You are asking for abiogenesis to be demonstrated (while dishonestly not even touching my presentation of it) and then declaring that unless we have the specific pathway then evolution couldn't have occurred.
This is akin to saying that unless we have a theory of everything then relativity is 'unproven'. Which is ridiculous.
The fact is, I provided an example which showed the chemical reactions of the Nylon bug - exactly what you asked for and now you are shifting the goal posts to include abiogenesis.
That is dishonest.

You are confusing faith with science. It is a model that has empirical support. It shows how it could have happened.
This is different from faith which has no empirical support.

Another strawman - science doesn't work off of being 'absolutely' correct. Nothing in science is absolute. Think about it, science is empirical. Is empiricism absolutist?
No.
Therefore you are being dishonest in requesting absolute certainty (and you are relegating all science into the 'might be correct' category, which you probably won't agree with).

YET I showed you how we reproduced evolution - the nylon bug - yet you have the audacity to say it's a belief hinged on faith?

I gave several other explanations - this is another demonstratably false statement of yours. What of saltation, lamarkianism, lysenkoism? Those were 'other explanations'.

This clues me in on the fact that you aren't very familar with science. Evolution is both fact and theory. Common descent is a fact, the theory of evolution EXPLAINS that fact.
That's what theories in science do. They do not 'become facts' as you seemingly suggest.
Here are some other 'theories'
Relativity (according to you, gravity is 'only a theory')
Germ theory (Germs getting you sick is 'only a theory', it's not certain and therefore faith!)
Heliocentric theory (the earth going around the sun is only a theory)
CREATIONIST organizations actually ADVISE creationists NOT TO USE that argument. Don't believe me? Here's a Young Earth Creationist website:
http://creation.com/arguments-we-think-creationists-should-not-use
"‘Evolution is just a theory.’ What people usually mean when they say this is ‘Evolution is not proven fact, so it should not be promoted dogmatically.’ Therefore people should say that. The problem with using the word ‘theory’ in this case is that scientists use it to mean a well-substantiated explanation of data. This includes well-known ones such as Einstein’s Theory of Relativity and Newton’s Theory of Gravity, and lesser-known ones such as the Debye–Hückel Theory of electrolyte solutions and the Deryagin–Landau/Verwey–Overbeek (DLVO) theory of the stability of lyophobic sols, etc. It would be better to say that particles-to-people evolution is an unsubstantiated hypothesis or conjecture.

I'm not so sure I believe you. You don't seem to have a good grasp on science.

Utterly and demonstratively false - You ignore the examples provided. This is YOUR mistake and misconception.

It is unreasonable to expect evolution, which is a theory that explains the diversity of life, to explain the origin of life.
Such demands show that you don't know what you are talking about. When I provide you evidence of the chemical process behind a speciation event and you then ask for the chemical processes behind abiogenesis, that shows me that you DON'T actually CARE what you are talking about.
Your mind has been made up. You don't think evolution happened and no evidence will change your mind.
