Argument #1: Transitional Fossils

[Anomalocaris]

Come on, all bible believing Christians known the earth is at the center of the universe, where can you fall off to from there?

Sorry to bust your bubble but the earth is at the center of the observable universe.

Sorry to burst your bubble, but whether earth is at center of the observable universe, and how far is the earth from the center of the observable universe, is a much more complicated and subtle question then you think. The answer depends on a lot more things than invariant speed of light. It depends on exactly how isotopic the expansion, and more importantly the acceleration of expansion, of the universe really is. Just how homogenous the universe was at the start of era of recombination after the Big Bang, did recombination occur exactly simultaneously or did it sweet through the universe like a wave. And is space itself really isotopic. Any deviation from perfect homogeneity and perfect isotropy will displace earth from center of the universe, likely by margins that are huge compare to size of solar system, or even the size of Milky Way. And unfortunately these factors are only not well constrained enough to tell us just how far earth would be displaced from center of observable, and observed, universe.

If more primitive ancesters of trilobites were found some time in the future, dating to before when you and your ilk thought there was a "sudden appearence", would you then admit transitional form exists and the biblical creation thereby proven to be bullshit?

If not, then how ingenuous can be possibly be in raising these objections?

there are changes that happen within species, but not species into a different species

Disingenuous, then.
