"I personally allow apparent age in a YEC scheme."
Ok, but that is one cynical God you have created there. Create the earth in 6 days and plant all kinds of fossils to make a young earth look old just to confuse the silly human scientists. Create humans capable of rational thought, say that the creation is "good" and then write a book that contradicts man's rational conclusions about the earth.
"The fact of Fish fossils on top of tall mountains screams global flood to many geologists..."
No, it doesn't. Only to YEC "geologists" of which there aren't "many", if any. It "screams" plate tectonics, is what it does.
