It didn't 'save it', just helped it to get the upper hand much sooner than it otherwise would have. With the decay and collapse of the Roman Empire, a religion that preached a close-knit society where believers helped each other and showed each other mercy would have - by default if nothing else - carried the day anyhow.

The 'mushroom cloud' following the meteorite's fiery impact might well have looked like a cross as it rose up - Roman crucifixion crosses didn't always have the spoke rising up the middle, and often were "T" shaped.

If it wasn't t shaped than where would they have tacked the sign on it?
