Why would we colonize the moon, when Mars is the best possible choice right now for colonization? Weird.
They're just starting off big first, then moving to something really big. They need a close to home test bed first for testing of needed life sustaining things such as growing food, producing their own water and oxygen, etc., as getting a steady supply from Earth would be too expensive and very impractical for sustained living off world. In short they need to be completely self sufficient without needing constant life lines from Earth.
Also with the moon being so much closer it's possible a rescue mission could be launched if something went wrong like a broken return vehicle, if that were on Mars they'd be screwed.
I watched that NatGeo program, and it was rather interesting, perhaps somewhat bold however it will one day be a necessity if an asteroid or comet hits the Earth, or a super volcano erupts devastating life world wide there could at least be Earthlings elsewhere in the solar system who could later re-colonize the Earth. Oh how nice it would've been to be born some thousands of years in the future!
