Am,F,G,C
This continues all over the song 
AmF You said "I come in peace", so I took you home
GC I gave you food and I gave you clothes
AmF I taught you how to move your feet when the rhythm's on
GC Still you wanna leave cause you feel alone
 
AmF You don't know what they're like if they know that you're alive
CG They're gonna try to take away the secrets of your planet's life
AmF I know you must be upset, you lost your family in a wreck
CG But you gotta listen (listen, listen)
 
Am Don't try to find your spaceship
F That might be out there waiting
C Stay in my backpack forever
G Stay in my backpack forever
Am You know I gotta find my spaceship
F My planet's outside there waiting
C I can't stay in your backpack forever
G Stay in your backpack, backpack, backpack
