Scientific Defense For a A Young Earth

This following link angers me a whole lot. It doesn't seem like much, but it is. It features many seemingly rational and compelling arguments agains the old Earth, thus supporting the young Earth. I researched every argument, and I found a valid refutation of every single one.

You may have to search some of the links to find the answers. A few of them I did not bother finding links for, since common sense was all that was required to provide a refutation (Or, the argument was just speculative and there was no real way to provide any evidence contradicting it).

Careful about those links. In your original link, about a third of the footnotes came from creationist references. In the links you provide below, half of them come from infidels or talkorigins-- sources that have a stated bias. Just as I would discount the creationist footnotes, so too as I would discount your links on the same grounds. I don't know how authoritative their remaining footnotes are. They may just be fluff-- footnotes to create the impression of scholarship. Your remaining link are from wikpedia. Wikpedia is Ok as a starting point in trying to find out about a topic, not unlike an encyclopedia in a middle school library or a Sunday newspaper supplement. But as a scientific resource, it is worthless and I would be embrassed to use it to support a scientific position. But what has more crediability are current peer reviewed scientific monographs.

I am not saying that your understanding of the points in question is incorrect. But you do need to improve on how you arrive at that understanding. The search for truth is hard work and there are no short cuts.
