M.T., great question. Bill Nye is not a prominent scientist. He's a TV personality with some science background.
An olive branch is good, but Ken Ham does not represent all Christians or believers. Ham once asked his audience, "Who do you believe, God or science?" Of course, his audience answered, "God." But Ham had loaded the question with a false dichotomy. It's not science versus God, but science versus Ken Ham and his limited and literal interpretation of the Bible.
There is a biblical timeline, for instance, that is compatible with those of mainstream science. The literalists (whether atheists or creationists) will never find this -- they will never see the spirit of the Bible where Truth resides.
I object to the debate on these grounds. Both Nye and Ham don't know what they're talking about with regards to creation.
Science studies the products of God's creation. Spirituality (the core of religion) studies the sources of creation. They are complementary. Nye doesn't understand this; but sadly, neither does Ham.
I have seen miracles that confound science and I've spent my life studying science, including astronomy, electronic engineering, geology, space science, computer science and more. It's fascinating to see both sides more clearly and how they work together in harmony.
I'm happy to be among the rare few who actually does change his mind occasionally, if I hear data and logic that is compelling. Like I used to believe in Anthropogenic Global Warming, until I investigate Climate Gate and found fudged numbers and fraud. Nye still has delusions about this. Too many scientists have jumped the UN's IPCC ship because of fraud (http://www.youtube.com/watch?v=YtevF4B4RtQ).
Concerning creationism, I believe in creation. I've seen some of it first hand (miracles), but I also believe in evolution. Ham has twisted science and scripture. He thinks death started with the Garden (Gen.3). But he's confusing spiritual death with physical death.
