All the claims that the earth is old from all the sources are still hypothetical so all you are doing is adding together hypotheticals from various sources and calling it "corroboration."
When every thread of evidence points to the same conclusion, that's the best corroboration you'll ever get. Creationists can criticize each individual method but they can't explain why they all get the same answer.
Those great preachers who gave into the Old Earth and tried to make the Bible conform to it have built a house of cards that subsequent generations can blow down with a breath, leaving them with very flimsy grounds for their faith.
The problem, though, is that it's the Bible that's wrong, not the earth. If your faith rests on the Bible, then yes, your house is built on sand.
Hey I like this post. I think I'll post it on one of my blogs.
More accurately, it's some interpretations of the Bible that are wrong, just as in Galileo's day his opponents wrongly interpreted the Bible to teach geocentrism.
Fair enough, but you have to jump through a lot of hoops to get an interpretation that matches reality. Geocentrism is a particularly bad example. While the Bible might not specifically dictate geocentrism, it certainly doesn't specify otherwise either. It's vague enough that you could shoehorn almost any shape of universe into it.
