Biblical explanation

The biblical explanation for how the Canyon formed is actually quite simple. The “basement” layers, consisting of granites and metamorphic rocks, were formed on Day 3 of Creation Week. Many of the other layers were deposited by the waters of the global Flood as described in Genesis 7–8. These unhindered, swirling currents picked up, transported and eventually deposited tons of sediment in layers. These strata were then tilted and bent through great tectonic activity during the final stages of the Flood. The sedimentary layers which make up the nine distinct layers of the third major division of the Canyon walls show that they were soft and unconsolidated when they bent, unlike the basement rocks which fractured. The sand grains in these sedimentary layers show no evidence that the material was brittle and rock-hard, and neither has the mineral cementing the grains been broken. Instead, the evidence points to the whole 4,000-feet (1.220 m) thickness of strata being still “plastic” when it was uplifted and bent. Once the Flood waters receded, the newly placed layers of sediment continued to harden into rock. As the Flood waters receded, the uplifted plateau acted like a dam wall, trapping the waters behind it. In a catastrophic event, this earthen dam ruptured, releasing a barrage of water that carved the Canyon itself.
