It's hard to say as there as so many. I suppose I would say that when I look at the amazing complexity of life and I read about the odds against all this occurring by chance, from a universe that no-one can explain in non-supernatural terms how it came into being, I just have to conclude that it's not possible, now matter how much time is allowed for it. Once there, I'm into theological issues, which is a whole new area of course (FYI, I don't accept the compromises of so-called Progressive Creation or Theistic Evolution because in my view, there is no evidence in the Biblical texts to support them and they just confuse the gospel message).
Don't be put off by the negative comments here - watch the DVDs and you will see how you are being deceived by all the evolutionist propaganda around us today.
