news.nationalgeographic.com/news/2007/08/070827-jupiter-comets.html"Many astronomers have theorized that the gas giant's gravity deflects possible impactors, making Jupiter one of several factors that made life on Earth able to develop undisturbed. But it turns out that if Jupiter didn't exist, some of those cometary invaders wouldn't approach Earth in the first place."I'm certain that there is some truth to the idea that life on Earth had endured due to a wide variety of pivotal circumstances but something tells me that though our existence might be quite different, sentient life in this universe was and is inevitable. Having said that I do find it fascinating to learn just how apparently precarious our world's fate seems to be.

The incredible balance of circumstances that makes life here possible is far more fragile than we realise. And yet, life is pretty tough too. Very few things could completely wipe out life. The period of finding a new balance would be chaotic, but I think one will always be found as long as there is anything that can sustain life left.
