"Biology teaches “heredity & variation” - i.e. built-in limits."
So if there is variation, and some of that variation is more 'heritable' than others (i.e. is varied) because, say, it better equips it's holder to make it to adulthood and raise a brood of sprogs that will inherit that variation in turn. Then what happens over the course of many generations?
Nearly there... You can do it... Just one more, little, teensy step...
"Evolution though teaches unlimited variation over time, and that heredity can be violated."
...and you fall flat on your stupid, vacant face!
Strawman! Evolution doesn't teach unlimited variation, never has, never will. Unlimited variation would mean every possible biological solution to a problem would evolve, be it wheels, rockets, or animal photosynthesis. Unlimited variation would mean there could be no heredity, every offspring has literally infinite possibilities to be different from you in every way.
"A creationist can predict that we live in an orderly universe - and we do! It was designed."
Predictions usually come before observations, that's why they're called predictions and not observations.
Name me one creationist who 'predicted' that the universe was orderly, before man new that nature has some degree of order?
"An evolutionist has faith to believe that nothing exploded into something for no reason, and oh yeah, gravity invented itself for no reason, and don’t forget the laws governing light, momentum, thermodynamics, etc. You see, at each step evolution defies science. Devout evolutionists deny the Creator’s power because she or he badly wants to ignore His laws regarding our lives and our morals."
Nuh-huh! We evolutionists do get around don't we. When we're not busy inventing godless theories of the development of life on Earth, we're off inventing whole fields of cosmology, geology and physics.
Psst! I'll let you in on a little secret; we also wrote the complete works of Shakespeare, and I, personally, design all the pope's dresses in between stints composing Beethoven symphonies!
"An evolutionist (to be consistent with his faith) should predict that we live in a disordered unlawful universe"
An evolutionist, to be consistent with his 'faith', should predict that the universe follow a system of natural laws that may be determinable from accurate observation of the universe itself and the application of rational and logical thought.
Methodological naturalism pretty much rules out 'goddidit' as an explanation unless you've got clear video footage of goddoingit, several key associates of god who are willing to pick him out of a line-up, and indisputable forensic evidence placing god at the scene.
"At each step of the way creation is in sync with science."
You're in sync alright, but unfortunately, you're in anti-phase.
