The difference between Mars and Earth is a little thing we call life. It’s OK to feel a bit proud when you see planet Earth from a satellite — she sure is pretty, ain’t she? All the water, and all that air, it darn sure makes for a beautiful, hospitable home. Zoom way in, and you’ll find people discussing their lives on a day-to-day basis, from the perils of dating to imagining what we’d do with a billion dollars. Speaking of unimaginable numbers, there’s about 6.8 billion of us roaming this planet, and we each have a story to tell. What’s yours?
