Of course i believe extraterrestrial life exists because the universe is so unbelievable big, the earth can't be the one and only planet who has life. i can't say how humans will discover but i think it would great if this discovery happend like in star treks: first contact. since i can think i'm a big fan of science fiction and for me it's an honor helping to find extraterrestrial life.
