matter of fact,

us humans are more than likely
Aliens on this planet

our physique and make-up was not
built to sustain us on this planet.
we have too many flaws as compared
to wild animals in their habitat.

a few examples would be our skins
inability to deal with mass amounts
of direct sunlight. animals do not
get sunburned, yet we humans do

another example is our skeletal system
was not built for heavy gravity planets
which is why most humans have back problems
before reaching age 50

another example would be our life span.

humans live to be around 80-100 yrs old.

Sharks, whales and dolphins and some
reptiles live a lot longer than we do.

it would appear that we humans were
transplanted here from some other place
where there was low gravity

which is why we are so short compared
to tall whites who exceed 12-15 ft
in height. they were raised in an environment
where little gravity allows their bones
to grow longer. excess gravity causes
our own weight to keep our bones from
their full growth potential.

we humans are the aliens here, IMO
