". . . what happened on earth" << Maybe try ' what happpened on this earth ' ?
" . . . when some thing's at birth" << that doesn't flow well - maybe changing " something is at ", i think it was just like off one syllable or something.
I love the meaning of this poem, darling. And, it's great. There were a few flow problems, but overall it was just perfect. You have a wonderful sense of what the world should be and who we all should be - now, if only it would happen, eh?
