After hearing about how harsh I am towards my fellow believers who believe in a young earth i decided to be a little nicer to young earth creationists. Now I just have to respond to this message by Ken Ham, where he states "living fossils" are a problem for evolution because a certain type of fish (the coelacanth to be precise) is still around which has been around for the past 400 million years. In answer to that, its not really one species of fish (it would be pretty incredible for a single species to survive 400 million years), it is an order of fish, and currently there are only two species remaining and they are critically endangered. It is not entirely unlikely that an order an animals could survive for so long, crocodillians have been around since dinosaurs.
Now one interesting thing he said is that some kids ask him if he's a living fossil, now what I am about to say is terrible but I am going to say and I apologize to my creationist audience in advance; because when he says he's a living fossil, he does look like our pre-human ancestors, and he sometimes acts as smart as them too so it would appear Ken Ham is a living fossil!
Anyway, that concludes my answer to Ken's answer, And Mr. Ham if you are reading this please take it in good humor (I have attempted to make this criticism as constructive as possible).
