People lived hundred billion
years with question "who are
we". Are we alone. What is in
other galactics and smth. They
lived without knowing this and
this tells us that THAT is how
it should be. we dont need to
know our history. we don't
need to answer these questions.
We need to explore and to
expand.
We need to explore as much as
we can. Also, i am quite sure,
that in a few hundred to a
thousand years Earth will be
overcrowded and we will need a
new place to go...
Exploring the unknown is a
good step for educational
purposes of mankind.
exploring other planets is
educational
i do not know anything about
this...
its good,i think..
Such missions are necessary
to look for life in Mars
