Many secular scientists believe there is very little or no evidence for a global flood which is mentioned in the Bible. Many of those same scientists however believe a global flood could have happened on the planet Mars. As we shall see, there is plenty of evidence for a worldwide flood which confirms the Scriptures.

"And GOD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually...And the LORD said, I will destroy man whom I have created from the face of the earth; both man, and beast, and the creeping thing, and the fowls of the air; for it repenteth me that I have made them...And, behold, I, even I, do bring a flood of waters upon the earth, to destroy all flesh, wherein is the breath of life, from under heaven; and every thing that is in the earth shall die.

-Genesis 6:5,7,17

Sedimentary Rocks

The Grand Canyon is one of many places which showcases evidence for Noah's flood. Evolutionists have dated these rocks based on assumptions between 230 million years old and 530 million years old. Generally when fossils are found, they get assigned an age which then dates the sedimentary layers. The concept is known as uniformitarian geology. The creationist paradigm predicts widespread, thick strata deposited quickly over vast areas of land. Generally showing little or no erosion between the layers.

What we find in the Grand Canyon is more consistent with the Flood model than with the uniformitarian model. We observe the formation of Cocoino Sandstone in the top of the Grand Canyon which can linked with sandstones in New Mexico, Texas, Colorado, Oklahoma and Kansas. When we look closer at the interface between layers in the Grand Canyon, we see little or no erosion which evolutionists claim to be many millions of years old. The average state of erosion on the continents would erode the layers to sea level in 10 million years. So the observational data is not even matching up to the evolutionist hypothesis of age.

In a flood especially a world wide flood, one would expect to find a highly diverse rock layer. And that's indeed what we find, as sedimentary rocks in the Grand Canyon are found all over the world, showing very little erosion between the layers. Evolutionists have noticed the regularity and parallelism of the layers which suggests the rocks were deposited in a single uninterrupted sequence. Something a flood could do. But their assumptions on how the fossils are dated are in direct conflict of what they see in the rocks themselves. So what conclusion do you think would an evolutionist take? Pretty obvious, he or she would take the dating of the fossils assumption instead. It's the main reason why many secular scientists try to deny the flood evidence. However, their denial doesn't change observational data.

The Fossil Record

In a world wide flood one would expect to find a massive and highly diversified group of fossils in a localized area. If there was a global flood, the water would carry animals from various parts of the world into localize areas where they are not known to have lived. And this is what we do find in the fossil record. Also, 95 percent of the fossil record consists of marine life. Marine life can degrade pretty quickly and would be a poor candidate to fossilize slowly over time. The animal must be buried quickly in order to ensure the creature being fossilized.

The Geological Model

A global flood would make a considerable and observable impression in the strata. One would expect to find a pattern consisting of buckling, bending, tilting, in the strata. Not a smooth flat layer. This would happen because of billions of tons of weight created by the flood would put an enormous amount of pressure on the earth's crust. The pressure would increase as the flood gets larger and larger, thereby creating downwards pressure, and also creating upwards and sideways pressure in non-flooded areas. When the flood regresses to post-flood levels, an imbalance of side pressure is created. Upwards pressure is also created when the massive weight created by the water flow is removed. Observational data reveals the geological model for the flood. The structure of the Pacific Ocean, Continental Divide, and Mississippi River Valley show the water had moved off the uplifting western United States, while seeing the water rushing toward the Pacific Ocean and down the east slopes of the Rockies. We also observe bent, and tilted strata in various parts of the world as the result of what the flood left behind.

Gene Pool Reveals The Flood

In a massive world wide flood one would expect evidence in a reduction in the gene pool, and that is what exactly what scientists have found.

“The studies, published in the journal, Nature, paint a picture of a population of humans migrating off the African continent, and then shrinking at some point because of unknown adversity.” ABC News

Mitochondrial DNA is most accurate form of tracing ancestral lineage. This is because Mitochondrial DNA is only passed on from mother to child and doesn’t mix with the other parent’s DNA. After mapping mitochondrial DNA, scientists noticed what is called a "bottleneck" in the gene pool. Now of course this study in itself couldn't ID the flood as the reason for the shrinkage in the gene pool, but it adds another factual observational fact, that the flood indeed happened the way the Bible said it did.
