I could see the images "painted" with words in this lyric. I do have suggestions for the verse about someone watching from space. It's the only verse that turns phrases around into unnatural orders, so I suggest trying to come up with something that works in a more natural order. Maybe something like....
Is someone watching us from outer (or "out in") space
thinking "what a mixed up human race"?
I kept the rhythm with strong and weak beats the same as you had them, but if there's wiggle room in the rhythm, you could probably come up with something better.
That's all I have. I do like the images of the lyric.
