"The number of fossils in some areas is enormous. How could earth have supported all those creatures at the same time?"

This question shows a common false assumption that many people make. They assume the earth today is the same as it has always been. Today’s earth is seventy percent under water. There are scriptural and scientific indications that the pre-Flood world had greater air pressure, higher percentages of oxygen and carbon dioxide, much more land (above sea level), less water (on the earth’s surface), and a canopy of water to filter out the harmful effects of the sun. This would cause there to be many times more plants and animals on the earth than there are today. The added air pressure would diffuse more gasses into the water and support a much greater fish population. Aquatic plant life per cubic mile would multiply also.

Second Peter 3 tells us that the scoffers in the last days will be willingly ignorant of how God created the heavens and the earth. They would also be ignorant of the Flood. These two great events must be considered before making any statements about the conditions on earth today.

Only about three percent of the earth today is habitable for man. The rest is under water, ice, deserts, mountains, etc. If the earth before the Flood were, say, seventy percent habitable, it could have supported a huge population. The vast amount and worldwide distribution of fossils shows that the Flood was global and that God hates sin enough to judge the entire world."

Dr. Kent Hovind "About 85% of the rock surface around the world is made up of sedimentary rock, indicating that at some time in the past, the world was covered by water."
