K's Choice - Time Is A Liar lyrics

A pretty girl in the desert with a heart the size of Alaska I thought I was too tired to talk but somehow I asked her Should I water the lot because nothing seems to grow? She said "yes, chances are it's getting better and we just don't know" We don't know who we really are Time is a liar talking to a star And we will know And then a landslide came and covered me with dirt We were choking and we cried for help then we were heard Mine girl I met in the desert who told me one more thing I am the seven billion people flying and we started to sing We don't know who we really are One day we'll dissolve into a star We will know Here we go What does it mean
