Who's to say whether our technologically advanced civilizations or these so called primitives provide a better way of life or happiness for their families while alive on this planet.. One things for certain. These people aren't messing with ours. If so-called evolutionary advancement means we forcibly intrude on people to become like us it brings into question whether we've advanced as humans at all.
If the day ever comes that we make contact with a civilization beyond Earth we all better hope they're not much like us. If we can't respect our own kind why expect they would?
