No I don't because that would be proving a negative! I am not required to prove a negative. If you positively claim that a natural mechansim that creates cells EXISTS, then it is YOUR obligation to prove it. Until then, induction leads to the belief that no such natural process exists.
>>Okay, and what does that have to do with the origin of cells? <<
A lot ofcourse. Untill we can track the individual movements of the molecular components, we're probably not going to find out why they apparently don't react.
But you are assuming that movements of the molecular components have anything to do with how a cell could theoretically pop into existence fully-formed out of biotic chemcials. Movements of molecular components have little or nothing to do with something as complex and integrated as the creation of a fully-formed cell.
>>We have had microscopes, laboratories, and all the resources necessary for the study of biochemistry/cellular biology for many decades, and all we have discovered is how much more complex, and irrudicibly sophisticated cells are than what we first thought.<<
The cell is complex, but not irreducibly complex.
Really? Then explain how a cell or pre-cell could theoretically survive without all of it's basic components.
>>What process? Do you mean the process that doesn't exist?<<
The process for which you STILL haven't proven that it doesn't exist.
I am not required to prove a negative. If you positively claim such a natural process exists, then it is your job to prove it.
>>That lack of understanding has nothing to do with the evolution of cells, and why that evolution has never been re-created in a laboratory, even when given all the same resources and conditions that would have existed on the primortial earth....and intelligent scientists manipulating the process to boot!!<<
I think that understanding the quantummechanical properties is very important, since they determine how the molecules interact whith eachother. If we don't know it, we cannot predict how exactly those molecules should be forming.
You're argument on this point is totally elastic. It could be stretched to support nearly ANY make-believe idea. For example, I could say alchemy is real, we just can't prove it because we "don't have enough understanding about quantum mechanical properities and molecular interaction".
>>That matters little if the specific natural process you speak of doesn't exist, or is powerless to create a cell.<<
Since noone has been able to prove that natural mechanisms are unable to form a cell, your point is rather moot.
No, you got it bass-ackwards. Since no one has been able to prove to any degree that natural processes are ABLE to create a cell, my point is perfectly valid.
>>We are not talking about "inventing" a new lifeform. <<
Yes, we are. We want to assemble a CELL from simple components. Should we succeed, that lifeform then IMMEDIATELY has to compete with all kinds of bacteria for survival. Those bacteria have had a several billion year headstart on evolution.
Erm, a cell in a not a new lifeform. Cells are well-known lifeforms that already exist. You body is made up of trillions of them. We wouldn't be inventing a new cell either, we'd be following the blueprints of cells that already exist. It would be like cloning, except starting from scratch. Furthermore, scientists could create the cell in a sterile habitat where no other bactierium exist, so your sqawk about bacterial competition is moot.
>>We are talking about re-creating a lifeform that already exist on this planet. <<
No, we're not. We're talking about creating a cell in the way we think cells looked like several billion years ago. Ofcourse, the cell still exists TODAY, but with several billion years of evolution it is likely that it has changed somewhat since then.
The simplest forms of cellular life are irreducibly complex. Therefore, there is no way they could have been any different billions of years ago. If a cell is not irreducibly complex, then all you have to do is explain how the interdependence of it's subsystems are not really "interdependent", OR, prove that there is such a thing as a pre-cell lifeform. If you can't accomplish either of those tasks, then your claim that the cell is not irreducibly complex is akin to a hair dryer.......It's good for nothing but "hot air".
