Well... it could be.
Especially now that they've found pure water ice up there, there's no telling who all came from or passed through the Red Planet on their way here.
When you review the literature, you see that a lot of the founders of world religions were ... well, in a word, nuts. They had visions, they glowed, they made their followers wander around in the desert and fight wars and build weird stuff; they communed with clouds and columns of smoke; they fasted for 40 days at a time.
You'd be nuts, too.
The weird thing about the story of the Jews is that the entire people followed this one guy (if contentiously) on a 40-year sojourn through a harsh, arid desert, where water was mysteriously conjured from the ground and food fell from the sky. All this after an encounter with a smoking, thundering mountain.
So -- just thinking out loud here -- what if the entire Jewish people's encounter with God consisted of actually lifting off and being transported to Mars?
Stay with me, now.
See, if there's water on Mars, there's oxygen (or if not, God could whip some up pretty quick); if there were no food, God would just drop some from the heavens. Presto: manna. The Jews panic and build the Golden Calf because we're scared to be removed from our home planet. Then we're sentenced to 40 years of wandering. On Mars.
Far-fetched you say? Say I: more far-fetched than the literal story? Oh, really? By how much? Omnipotent God, right? Made everything? Can do anything, blink of a cosmic eye?
I say those Mars rovers should be looking under their wheels. Maybe it's not that there aren't any archaeological artifacts of our sojourn in the wilderness.
Maybe it's that we've been looking on the wrong planet.
(Or maybe I've had a few too many...)
