Walking the moons of mars

I have seen the clouds from above
and travelled between stars
I've seed them fall in love
I've walked the moons of mars

The universe is nothing new
The things unknown to me are few
I've seen the birth of our sun
and beed there when all life begun

But I cannot understand
when my life will end?

I have sailed the seven seas
and did it very well
Created summer breeze
I thought you'd like the smell

But I cannot understand
when my life will end?
