Answer 1

Answer:

You can't see me, yet I'm there

Under blue or red, white or black

I decide if you will live

I can put you to sleep

I'm with you, as you can see

Whether home, on space or sea

There's no use running free

You'll be rendering your life useless

I can harm you, I can kill thee

Yet you crave me and you seek me

Mark me and follow me.
