Spark of life: Metabolism appears in lab without cells

[jerryR34]

again with the false dichotomies...(even though you said it wasn't).  Did you even read the article I posted?  Am I to value your scientific opinion over those in the article?  We did that centuries ago, it was called the dark ages when the powers said that things can't happen and science proved them wrong.  I don't see the logic in you argument that there can be only one creator...you are building your own logic there.

Claim CB015:

DNA needs certain proteins in order to replicate. Proteins need DNA to form. Neither could have formed naturally without the other already in existence.

Response:

1. DNA could have evolved gradually from a simpler replicator; RNA is a likely candidate, since it can catalyze its own duplication (Jeffares et al. 1998; Leipe et al. 1999; Poole et al. 1998). The RNA itself could have had simpler precursors, such as peptide nucleic acids (Böhler et al. 1995). A deoxyribozyme can both catalyze its own replication and function to cleave RNA -- all without any protein enzymes (Levy and Ellington 2003).
