I must first apologize, for I am not well informed on the subject of abiogenesis.
A colleague and I were debating evolution which due to his ignorance on the subject leads to an argument over the origin of life and abiogenesis. He claims that a man by the name of William Pratt has carried out an experiment which disproves abiogenesis, am I correct in assuming that the only thing he proved was that bacteria can not be created from non-organic matter which is totally irrelevant?
