confirmation that there can be life on other worlds and that the earth isn't unique.
lol.
seriously??
if you don't think that there can be life on other worlds you're fooling yourself.
Earth is not special. humans are not special.
it's not like we're made of anything special.
we are arranged from the simplest and most abundant elements in the universe. the Earth is only unique in our solar system; it's not even unique in our galaxy, let alone our star cluster or the rest of space.
a rudimentary understanding of biology and astronomy should lead anyone to realize that complex life is not unique or rare
in spite of the fact that we haven't found it anywhere else. especially when "anywhere else" accounts for barely 0.000000000000000000000000000000000000000001% of the known universe.
