I think you are missing my point. Creationism is not a belief formed on the basis of scientific evidence, so asking for the scientific evidence for it misses their motivation. You are right that there are plenty of creation 'science' web sites. I have yet to see one that actually made a case for creationism, rather than simply bashing evolution (and rather ineptly at that).
Well the date of creation as being 4004 BCE was worked out by Bishop Ussher, so why would he lie, he was a man of God.
Yeah, lying was a poor choice of word. Wrong might be better. Incidently I found this
http://www.lhup.edu/~dsimanek/ussher.htm about Bishop Ussher's estimate, it's kind of interesting.
He worked these dates out from the very genealogies that you cite, but by your calculations as well, you are asking us to believe that the universe is no older than 7000 years. Yet you base this on nothing except the claims of an ancient mutli-edited text and a probable psychotic episode that shortcircuits your rationality.
Not mine, matey, not mine. Merely describing the other side as I see it.
Finally, if my argument is a strawman, why are so many christians campaigning to have creationism taught in High School Science departments?
Because they see the science of evolution as a direct threat to their religion, and therefor false. Do you want your children (or hypothetical children if you have none) taught something you believe to be false as scientific fact in the classroom?
