well, frogprince, please don't feel you have to visit the Kentucky ark and part with your money. Kentucky will do very well out of it just by people that think it worth paying to see. and the construction costs are largely privately raised, is taxpayers money involved ?,- there is expected benefit to that states economy. compare that to taxpayers money funding Darwinist beliefs!. all you need to do is look on creationist sites for most of the answers to your questions.....not claiming that you will accept those answers, but I think you will find them a lot less simplistic than you suggest they might be.

dmcg it did seem to me that you were claiming scientists impartiality but thankyou for some measure of clarification.
re-your 2 observations-
A, We don't know everything but the evangelistic zeal of evolutionists here certainly contradicts that notion.....except when they have to eventually change the details of the story.
creation believers know that they don't know everything, but are upfront about their presuppositions.
B, what evolutionists think they know has already been contradicted by experimental, testable, repeatable science, but the alternative of " allowing a divine foot in the door " is clearly unpalatable to atheists.

shimrod- I am not able to quantify how much if any, amounts to "conspiracy", how much to the bias in education, how much to peer pressure, or fear of job loss or sidelining from advancement. certainly I believe there must be an element of deception/delusion involved, for educated people to believe unproven and impossible things. [ the fact that some Christians also believe some of this stuff, in contradiction of the book they claim belief in, only testifies to the success of the deception].
over all is a spiritual blindness, I believe. the devil "is a liar, and the father of it" john 8v44
so there is my answer, shimrod. I expect you will argue the toss, but it is not my intention to argue over it, but to suggest some explantion , though not exhaustive.
