"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." Peter and Paul Lalonde, 301 Startling Proofs &
Prophecies
