How Do I Know lyrics

How do I know that those mountains aren't cardboard How do I know that the world is round Why should I know just because you've told me There's molten rock underneath my ground How do I know there's a god in the sky Looking down and hearing me Why should you say I can't love any man Have his children and still be free Go on voting, striking and fighting Go on searching, hiding and laughing I can't change you I can't even try But let me live like I think I can Then when it's time for me to say goodbye I'll have lived just a part of man Go on voting, striking and fighting Go on searching, hiding and laughing I can't change you I can't even try But let me live like I think I can Then when it's time for me to simply die I'll have lived just a part of man
