Just being “alive.” We become alive, some sort of “spark of life” pulses through us, and at some point, that “spark” leaves us, and we are nothing more than a rock. What is that “spark?”

Everything is either animate of inanimate, so how did things become animate? At some point, something had to get that “spark,” and become alive, then spread that life around. How did/does that happen?

Is this “spark” unique to Earth, or is is possible to exist elsewhere? Did some nearly impossible combination of factors all happen to line up and cause “life” to emerge, like a room full of monkeys randomly typing Hamlet, or do those factors exist in other places?

Of course, many people would assign a religious explanation to that “spark,” our Soul or whatever, but that’s just making up a silly story to explain something we don’t understand.
