It's odd that after discussing the features that make life on Earth possible for us, with all the fine tuning etc, that Dr Karl and Dr Lewis can't see that it looks like someone took great care to design a safe and stable habitat for us. And when asked how life could have got started, Dr Lewis spoke about environmental conditions but never even touched upon the biochemical hurdles, such as needing numerous molecular machines in place and functioning to get self-replication, which the allows...

OMG this is insanity! Prof Lewis claims that we rarely see a smashed glass come back together and reassemble itself! (RARELY...? Has anyone in all of history EVER seen this?!) But he claims it is possible! All this nonsense (non-science!) just to avoid the implication that evolution is impossible because natural forces cannot create ordered complexity. Only an intelligent mind can do that. For much better explanations, search for articles about entropy on www.creation.com

OMG what drugs is this prof Gisela Kaplan taking?! She said "You never get anything in evolution unless it's absolutely necessary for the survival of the species." So how does painting beautiful pictures help us survive? Or composing music? Or playing the violin? Or performing a dance routine? Or ride a unicycle? Or work out abstract mathematics? Or how does a peacock's tail plumage help it survive? (The females don't choose mates based on tail plumage.) These evolutionists are mad!

His female guest made the comment that wherever on Earth we find water we find life, then makes the leap to wherever in the universe we find water we're likely to find life. Wrong! Finding life on Earth always in the presence of water shows that water is NECESSARY to SUSTAIN life, but it doesn't mean that the presence of water is SUFFICIENT to ORIGINATE life. The molecular machinery in living cells shows clear signs of very clever design, pointing to a very clever Designer.
