The problem with tweaking it toward creation, in the sense of instantaneous appearance of animals, is that...
What is Gods logic behind it?
For example, why create a paleonmastodon, then destroy it, then create something like a paleomastodon but a little different, then destroy it, then create something slightly more different and destroy that, on and on and on?
Why create a theropod that has feathers and looks like a bird, then just whipe it out, then instantaneously create a bird with theropod like features, then just instantaneously whipe it out, then create a bird?
Why create fish, then wipe the fish out, then create fish that seemingly have legs and amphibian traits like an opposable neck and shoulder bones, then wipe that amphibian like fish out, then create an amphibian?
What is the logic behind it? And further, why does this logic, match genetic phylogeny? Why can a geneticist who knows nothing about fossils, make a prediction based on the DNA of amphibians, where a fossil like tiktaalik would be? Tiktaalik could have been found anywhere on the planet at any depth beneath the earth. But it wasnt anywhere, it was right where it was predicted to be based on evolution.
If instantaneous creation were the way God created life, it would appear instantaneously, it wouldnt appear as a succession of fossils.
And this is the question that, I have yet to hear any creationist (instantaneous young earth creation) answer.
