Well kung titinignan mo,, vast ang universe so it is not impossible that we are the only one living here. There are alot of galaxies and planets out there. Yung constellation na Big Dipper ata or little Dipper yung last star,, hindi star yun galaxy siya. Also remember na upto now nag e-expand parin yung universe, thus there is also a creation and destructions of planets, stars or kung anue man yon.. (ー_ーゞ)
