OP,
Your original question just causes people to run in circles because the anti-creationist school of thought is essentially one school. Variations in opinion are relatively minor. Creationists on the other hand are often quite different in their opinions of the creation/creator.
So you end up with a group of people who essentially believe the same thing debating another group who don't agree amongst themselves. Doesn't make for a very good debate.
To have any serious debate you must define God. In any case I'll reply to your post not to try to prove the existence of a creator, but to offer some different suppositions and perspectives.
As some have pointed out, the Bible says the earth was "good", not perfect. So what was God's purpose? Let's assume that this planet was created specifically for what we call modern man, and that this isn't just extreme arrogance. Then let's assume that God wishes for man to progress in knowledge and understanding, but only in a line upon line context.
As hunters and gatherers the next gain in knowledge would lead us to agriculture and to permanent construction. But relatively recently our "advancement" would require what we call the industrial revolution. Without oil, gas, petroleum, etc. we would never have advanced as far as we have today. These extinctions you refer to have provided us with the necessary fuel and an earth suitable for the life of modern man.
I'm not trying to be rude but your point is irrelevant to many creationist believers. You need to remember that they believe the earth was created for man, not for all the other species. Therefor, extinction of other species as we know it simply makes the earth more suitable for the inhabitants it was specifically created for, and at the same time providing the fuels necessary for incredible advancement.
