Let it be know that I have viewed the site creationsafaris.com in the past and I did so again before posting this.
That is a YEC site. Do you know how many different scientific disciplines have to be wrong for YEC to be correct?
Never mind the label of YEC. This website has plenty of explanations of the fallacy of evolution. Don't fall for the evolutionist's smear tactics - YEC has nothing to do with biological explanations. If you do find an article on young-earth creationism, then JUST SKIP IT. But be honest, don't avoid the website, then point to fellow freepers and accuse them of a lack of scientific knowledge. I've asked a former freeper (banned during the Great Evolutionist Purge of 2007) how many years of study would it take a typical person to have a sufficient understanding of biology, archeology, geology, etc. to be able to refute him. He would not answer.
All of your questions on evolution, biology, etc can be answered at this site, www.creationsafaris.com.
I have no scientific background, but I can understand David Coppedge's explanations of the fallacies of evolution.
To answer the question, I do not know how many. Except for biology, and of course evolution (which is NOT a serious scientific discipline, it is a belief system for scientists). If you want, you can give a ballpark number.
