Dear Paul, The following is a quote from the attachment I sent you. ' Therefore left-handed chirality in the amino acids of life are an absolute necessity. However it has also been discovered that nucleic acids are all right-handed. Therefore Miller's racemates are useless for abiogenesis.' This should explain your 'contradiction'. Paul said... It would be lethal to a cell, by preventing metabalism, if a right-handed molecule was inserted. Therefore all cells have their metabalism lethally prevented, making life is impossible. But life exists. E-r-r-o-r -- d-e-s-t-r-u-c-t -- e-r-r-o-r ............ With respect Paul your statement is nonsense and is answered above. Therefore life exists because there is no mixed chirality. Regarding 2nd L.O.T., I gave you a link to a website that explains it fully - have a look at it. Paul said... This is not a discussion starter -- you've made it plain you won't engage. However I will make a statement. Life exists. It is perfectly reasonable to explore the possibility of evolution acting on existing life. Many problems -- not just the mechanism of evolution -- can be attacked by simultaneously addressing different parts of the problem. It happens all the time! Often referred to as parallel processing. I agree with what you have just said but as I previously stated I will not get drawn into digression. Before discussing how to build a skyscraper it would be prudent to figure-out what kind of a foundation it will need. You could speculate on using sand or wood or rock, but a little experimenting and a little research will soon tell you that sand and wood would be useless. However I will just make this one comment about your statement above. Yes evolution does act on life today and that is why there are so many variations within each kind of animal (microevolution). However evolution cannot account or demonstrate the transition over time of one kind evolving into another kind (macro evolution). Cats have always been cats, spiders have always been spiders and humans have always been humans. Don't be tempted to start talking about 'Lucy'! Regards Jack ...because without it there will be nothing to evolve. This is not a discussion starter -- you've made it plain you won't engage. However I will make a statement. Life exists. It is perfectly reasonable to explore the possibility of evolution acting on existing life. Many problems -- not just the mechanism of evolution -- can be attacked by simultaneously addressing different parts of the problem. It happens all the time! Often referred to as parallel processing. You've detailed some difficulties of dealing with evolutionists. Well others have difficulties dealing with creationists, especially fundamentalist creationists. The immediate problem I see is an inability to deal with part of a problem. Such people need certainty in everything and of course this is not possible if the problem is incomplete. Paul D
