Earth Was Alive for Billions of Years Without Us

Earth was alive for billions of years before humans appeared. For much of that time, a visitor could have found a living planet whose air we could not breathe. What took so long?
One explanation is that the evolutionary transitions leading to us were extraordinarily unlikely. Another is that the planet itself needed to change before those transitions became possible. Ancient rocks, low oxygen sponges and evolving yeast help reveal why the difference matters. But the two explanations may be harder to separate than they first appear.
From Galileo's search for life on Earth to the atmospheres of distant worlds, this documentary follows the evidence behind our late arrival, and asks what could tell us whether another living planet would ever produce someone able to ask the same question.

So while Earth was developing we don’t know if it had visitors or what civilisations have existed here. Earth is billions of years old and we only speculate on the last hundred thousand years.
We don’t know how far space reaches in any direction or if just goes on and on in every direction. We don’t know what is happening out there to other beings, their planets or the future of space.
Whatever our idea of the entity of God, what if he only exists in this place called 'the future'? If that is even the slightest bit true, what that means is that, as humanity proliferates the ability to affect the planet; it is developing an ability to affect God.
God may not decide if humanity gets to survive. But rather he is the decision itself. The result of our combined actions is, essentially, God.
