steve-the quote was an admission from an evolutionist;though of course i agree with it .you claim continuously that the weight of evidence supports darwinism,though admitting many gaps,yet the very foundation of the GTE is scientifically improbable to say the least.
i am sure abiogenesis is a massive problem for evolutionism notwithstanding hawkins efforts.
but thankyou to you and penny for explaining your position on diamond contamination.i am not personally equal to pursueing the argument but it is helpful to know what the argument is.
