We Are Almost Not Here (Part 2)

This is the second part of my two-part series on how we are almost not here at all.

In the first part we saw, from a cosmological perspective, how the laws of nature - which do not necessarily have to be the way they are - have only just enabled life to be possible in this Universe.

Granted that cosmological laws have enabled life to be possible in this Universe in the first place, we'll see, just from the perspective of this one planet Earth, how once again we are almost not here at all.

The Universe, and our Galaxy, is a dangerous place. There are many natural phenomena that can lay waste to a planet in a single instant. Somehow on Earth we have been lucky, and have been spared total annihilation over the 4.5 billion years life has been here. But for every 'lucky' planet like the Earth in our Galaxy, perhaps there are countless dozens that weren't so lucky.

Even without planetary disasters, the evolution of intelligence - let alone human beings - is by no means guaranteed. Evolution can only take just some of the many possible paths available to it. This is largely dictated by environmental factors beyond any species' control. The evolutionary path to the human species on this planet did not necessarily have to be followed and, in this respect, we can think of ourselves as only just being here.

I hope you enjoy the second part of 'We Are Almost Not Here.'
