Hello Chitty and welcome to EvC.
One rule we have around here is that we don't debate websites. You need to put forward any arguments you agree with in your own words and use sites as a reference to certain facts that underpin your views.
The site you reference starts of with a lot about the age of the earth. That doesn't belong here as much as it belongs in the "Dates and Dating" forum.
You probably should start by reading over:
Age Correlations and an Old Earth: Version 1 No 3 (formerly Part III)then if you have answers to the points raised there please post them.
