Maybe pagans are that dumb, but most informed christians realize the truth, that a lot of the early Bible is allegorical in nature. There was a time in which the Church nearly put to death Galileo, one of the greatest intellects in history for saying the obvious, that the Earth revolved around the sun. You have to understand that if YOU had been alive at that time, with your mindset, you would have joined the clamor to hang this man for stating the obvious, as your are essentially doing now.
And today, the pendulum has swung the other way, where evolution belongs in the stone age. New sciences are opening the door to something even greater.
And you sir, are full of it. I am a Christian, and I believe what Jesus taught. He affirmed the old testament, and He is credited in the new testament as the "Creator of all things". An "informed christian" as you put it, should know that much, at a minimum. I don't know who you are talking about, but they are certainly not Christians in the sense that they are followers and believers of the Christ.
I don't believe the allegorical nature of the Bible was being discussed here.
