What reason would God have for making all dating techniques point towards the same conclusions?
I have similar ideas to GFC every now and again, but with some important differences. To me, God is about love not science. I see the Earth of Creation as a very simple place, no complicated atoms and forces... it just is. People are really made of animated clay. After all, the important bit is the spirit/soul and it just needs a vessel.
The Fall happens (for reasons only hinted at in Genesis) and God departs leaving Lucifer/Satan as Lord of this universe. Now Satan is much more the scientist, and HE does a spot of recreation erasing all the aspects he can of God's initial work... and volia, the universe as we know it.
Ok, ok, a little too Milton on acid... BUT it does provide the perfect rationale for the YEC:
1) The real truth is that the Earth IS young
2) The fossils WERE "placed" there to deceive
3) Scientists ARE doing the devil's work.
It's so obvious when you think about it
