Marble is metamorphic limestone. Any stone mason that claims they make marble is full of crap. Clearly you do not have a grasp of the most basic understanding of geology.

Marble is a rock resulting from metamorphism of sedimentary carbonate rocks, most commonly limestone or dolomite rock. Metamorphism causes variable recrystallization of the original carbonate mineral grains. The resulting marble rock is typically composed of an interlocking mosaic of carbonate crystals. Primary sedimentary textures and structures of the original carbonate rock (protolith) have typically been modified or destroyed.
Pure white marble is the result of metamorphism of a very pure (silicate-poor) limestone or dolomite protolith. The characteristic swirls and veins of many colored marble varieties are usually due to various mineral impurities such as clay, silt, sand, iron oxides, or chert which were originally present as grains or layers in the limestone. Green coloration is often due to serpentine resulting from originally high magnesium limestone or dolostone with silica impurities. These various impurities have been mobilized and recrystallized by the intense pressure and heat of the metamorphism.
Its doesn't make sense. I mean what about dinosaurs and all the really cool things science has found.

Nobody ever said the world was millions of years old before Darwinism, precisely when noticed that finches don't make penguins.
The old earth idea is older than Darwin and became accepted science before he returned from his journey.

So you have evidence that the decay rate of these isotopes can change? Last I checked, the earth's environment is constantly changing, yet the decay rate does not.
The water vapor canopy hypothesis would neatly explain yet another observed anomaly…too much water in Earth’s upper atmosphere. NASA satellites have confirmed far more hydroxyl in the hydrosphere than current models predict. The parent molecule of hydroxyl (OH) is water (H2O). Because ultraviolet radiation from the sun breaks down water in Earth’s upper atmosphere into hydroxyl and hydrogen, a large amount of water must have previously existed. Some have proposed a constant influx of mini-comets as a source for the mysterious water, but that theory has been strongly criticized as unworkable. (Matthews, Robert, New Scientist, July, 1997, pp. 26-27.)
Another interesting feature of the early earth atmosphere was enhanced oxygen. The analysis of microscopic air bubbles trapped in fossilized tree resin gave Robert Berner of Yale and Gary Landis of the U.S. Geological Survey a glimpse into the ancient past. “The researchers clamped the amber into a vacuum chamber of a quadrupole mass spectrometer, a device that identifies the chemical composition of a substance. As the machine slowly crushed the sample, the microscopic bubbles were released, exhaling up to 100 billion molecules. These breaths disclosed some surprising evidence: the ancient air contained 50 percent more oxygen than the air today.” Landis believes that the reduction in oxygen could have led to the dinosaur’s demise. (Discover, February, 1988, p. 12.)
Other studies of air bubbles in amber have found increased pressure as well as greater oxygen levels. “One implication is that the atmospheric pressure of the Earth would have been much greater during the Cretaceous era, when the bubbles formed in the resin. A dense atmosphere could also explain how the ungainly pterosaur, with its stubby body and wing span of up to 11 meters, could have stayed airborne, he said. The spread of angiosperms, flowering plants, during the Cretaceous era could have caused the high oxygen levels reported by Berner and Landis, scientists said last week.” (Anderson, Ian, “Dinosaurs Breathed Air Rich in Oxygen,” New Scientist, vol. 116, 1987, p. 25.) A Yale study published in the March 3, 2000 issue of Science independently confirmed the high levels of oxygen present in the earth’s distant past. Some have even suggested that without such an atmosphere the relatively small lung capacity in certain dinosaurs could not have supplied their massive tissue with the needed oxygen.
In October 2006 Science Daily publicized a study led by Arizona State University staff entitled “Giant Insects Might Reign If Only There Was More Oxygen In The Air.” The article claims, “The delicate lady bug in your garden could be frighteningly large if only there was a greater concentration of oxygen in the air, a new study concludes. The study adds support to the theory that some insects were much larger during the late Paleozoic period because they had a much richer oxygen supply, said the study’s lead author Alexander Kaiser. The Paleozoic period…was a time of huge and abundant plant life and rather large insects — dragonflies had two-and-a-half-foot wing spans, for example. The air’s oxygen content was 35% during this period, compared to the 21% we breathe now, Kaiser said.” This research concurs with the biblical model of the early earth. In 2010 researchers at Arizona State University presented the results of experiments raising insects in various levels of atmospheric oxygen. Ten out of twelve varieties of insects studied decreased in size with lower oxygen. Some, like dragonflies, grew faster and became bigger in an enriched oxygen atmosphere (Science Daily, October 30, 2010.).
