The Human Purpose.
None has been made visible
and none been agreed by all human-beings.
However, it is being researched,
and sufficient evidence been already uncovered
that
our Human Race
and our Civilising activities
was instigated
and is being driven along
by intermittently-visiting more-advanced
ET-Beings from elsewhere in our Local-Galaxy;
and also being ‘deduced’
that such ET’s,
‘though much more advanced than our Humankind on Earth,
and ‘though also at least hopefully ‘well-intentioned’.
nonetheless rather clearly do make mistakes.
Their ‘fallibility’ in turn sometimes makes it look as if
those Extra-Terrestrials are “merely-experimenting”
with ‘our’ human-race.
