Mount Toba blew 800 cubic
kilomenetrs of ash 71,000 years ago. Most of India was buried under it. But
the worst was yet to come when it ensued the global volcanic winter for 6 years,
which probably killed 75% of plants in the Northern Hemisphere. The
constant reflection of the heat from the snow back into the space pushed the
Earth into a thousand-year ice age.
I believe that humans
survived in isolated pockets through out the continents. The Urals are a
good possibility - a very old mountain with good fertilizing sediment exposed,
with a lot of protection, and wildlife. And the same can be persued through
other continents.
From time to time, Earth
does her cataclismic tricks. 540 millions ago, the buildup of continents at
South pole flipped her to the current 23 degree tilt.
What if Earth is much much
older? Big mistakes were often made at estimating cosmos. What if we lived much
longer than is known? Many times humanity was wiped out by disasters almost to
the last one of us.(Even the Book tells us so). But we kept on multiplying,
developing particular traits, and then we meet at the crossroads, and argue who
was there first.
Sincerely,
Adriana K.
