Oldest Dwellings
I was searching the web for Rev Adam Sedgwick's famous recantation speech, and happened to find this site. One of the posters here had the misconception that there are no archaeological remains older than 4000 BC. Since I have personally worked with material older than that in a museum setting, I thought I'd post a link about the oldest human habitations.

There is a lot of material about the hut in Japan. I first read about it on the BBC website.
I think, if you want to maintain a faith-based view of a young earth, the easiest thing to do would be to ignore these archaelogical finds. Failing that, it would be simplest to assert that the dating cannot be correct.
In any event, I hope the link proves of some use to you in your search for truth.
