I don't know if extraterrestrial life exists. But I believe in other livable planets, so it can be true that there is extraterrestrial life. The danger if we discover that we kill that extraterrestrial life to use the planet to live on. I think we have to send a beacon into space because if we don't find them. Let them find us!
I am participating in SETI because my computer is always chilling and now he is doing something in his free time.
