A - RAIN:  The deposition of water on the Earth's surface was entirely by evapouration and condensation until the Flood.

B - CLOUDS:  Neither clouds nor a rainbow were visible before the Flood.

C - DROWNING:  Approximately 3 billion had never been seen in the oceans.

D - NO LAND:  The earth's inhabitants had always seen the ground up until the start of the Flood.

E - GIGANTIC SHIP:  No one had ever built any vessel before, like the Ark.

F - MIGRATION:  Men had never seen tens of thousands of animals migrating to one spot on the landmass, without human control.

G - ABOLITION OF TIDES:  The usual coastal sea tides had always been seen all around the world.

H - RAINBOWS:  As there were no clouds for rain, there could not have been any rainbows over the Pre-Flood earth.
 

I - EARTHQUAKES:  Land movement has marked all centuries since the Flood, with faulting or orogonies of mountains continuously.

J - FOSSILS:  It is assumed that most, if not all fossils, were formed during the Year of the Flood as the sediments were then available to cover the carcasses and preserve them in the rock formations.

K - SEASONS:  The Divine intimation to Noah that the weather would change yearly intimates that the Pre-Flood climate was equitable all over the Earth and the Poles.

L - MEAT-EATING:  Human diet was vegetarian until God gave permission for man to eat meat.

M - BLOOD-SACRIFICE:  God-fearing humans may not have killed animals until Noah's sacrifice after the Flood.

N - WEATHER PATTERNS:  These developed due to the Polar icecaps and temperature differentials and rates of evapouration.

O - WIND SYSTEMS:  Our modern wind belts originated soon after the Flood when air streams above the land masses started to vary in temperature and humidity.

P - COASTAL EROSION:  Land movements, both uplift and faulting presented the oceans with sediments capable of erosion, aided by strong seasonal winds.

Q - RIVER SYSTEMS:  The variation in land-formations, different altitudes and rock types gave rise to fast and slow flowing rivers, helped by a new pattern of rainfall over the new continents.

R - DESERTS:  Possibly there had been no deserts in Noah's early life as the world's vegetation was universally covering the pre-Flood landmass in considerable density.

S - VEGETATION TYPES:  The varying new weather encouraged the development of numerous completely different ecological systems which encouraged groups of plants suited to that weather and climate.

T - TRANSPORT:  The usual domestic animals of burden were bred for different routes and climates, and man started to construct water transport vessels, such as barges and sailing ships.

U - COMMUNITIES:  Mankind soon became grouped into different civilisations after the Dispersion of Babel which was Divinely sent.

V - TERRITORIAL POSSESSION:  Unregenerate mankind, away from the Almighty, soon became aggressive and fought for land claims.

W - CRAFTS:  Man's ability to handle various media such as clay, wool, thread, straw, wood and stone soon resulted in national crafts which were put to good use as food and water containers where suitable.

X - LANGUAGES:  The Divine Imposition of languages and dialects was unalterable and, of course, it has persisted throughout time.

Y - WEAPONRY:  The evil hatreds in mankind, stirred by Satan, soon produced numerous different weapons of war.

Z - JUDICIAL SYSTEMS:  Even evil mankind realised the need for the administration of justice, whether according to the Divine Standard or not, this led to forms of government, courts and legal systems.
