Time Is A Liar

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
