The truth that is avoided by the media is this: It's not so much where "mankind" got it's start but where it has gone. I'd say turd world slimeball lands are still in the stick-in-the-mud age. I can see why the smarter beings would've moved elsewhere.
But really, I don't think mankind started in just any one place. Just like the wheel, it was invented numerous times but which cultures evolved to the point they actually put it to productive use?
For the cucktards, it's not where it all started but which culture got us to where we are now and where we will be in the years to come.
