I sometimes wonder about how life came into being because something can't be created out of nothing according to our understanding. And if there's a God (explosion, alien, ect.) what created him or it, or did it even have an origin or a birth? Science has a theory about the begining of the universe involving parallel worlds. According to this, anything someone does at this giving moment his doing the exact opposite in another universe, its preaty crazy.
