Now, wikipedia isn't a flawless source, but it gives a nice background on where Young Earth Creationism gets it's info. It's based on the interpretations of an Irish protestant Archbishop in the 17th century.

Personally I think the whole Young Earth Creationist thing comes directly from this guy's teachings. And his understand could have been launched by a mis-interpretation and heavy extrapolation from St. Augustine's writing in the 4th century (he wrote several interpretations of Genesis, ONE of which was called the "literal" interpretation of Genesis; note that it was just one of several possible interpretations, yet somebody obviously seized on this new idea and decided that it was the ONLY one).
I'm reading Augustine now so I'll let you know if I find anything interesting, but it might be awhile (he wrote a lot!). Suffice to say I think that YEC is bunk, and I see no reason to accept it as a religious person. For now I'm more of the mind of theistic evolution. However I don't accept evolution as a religious belief, but as a scientific theory. I allow room for advances in our understanding, so even if it was somehow proven false (unlikely as that might be), it wouldn't destroy my faith. The faith part, for me, is that God was ultimately responsible for the universe, that is, it wasn't just a random meaningless accident. And this still allows for humans to have a "personal relationship" with said deity through prayer, virtuous living, building a peaceful and just society and private & communal mystical experience.
Edit: It appears from the link above that the Venerable Bede (8th cent) and Scaliger (17th cent) also postulated similar "chronologies" but I haven't read their works to say for a fact how similar they are. I just know that Ussher is widely quoted as being the one with the dates.
The kicker seems to be that if this guy was correct, the world should have ended by now! Anyways...
So yes, teaching YEC in schools is a mistake. If you're going to do that, then you should also teach Intelligent Design, the creation myths of various other cultures, etc, in a RELATED section to show the cultural responses to Science, not as the science itself. It's okay for people to learn about these things, but it's not okay to eliminate the scientific facts as the majority of experts know them to be today in favor of one small set (or subset) of religion's teachings.
