Yup. No one can answer, as there isn’t an answer.
Also, try this mental exercise:
Imagine you are an alien explorer from a far distant galaxy. However, you can only visit the Earth every 50 million years or so. How many times could you have visited in the entire history of planet Earth?
80.
4 Billion divided by 50 million = 80.
That’s a lot of visits!
Now imagine your last visit. 50 millions years ago the Earth was in the Cenozoic Era in the Eocene Epoch. There was no ice caps, anywhere. The Earth was warm, with palm trees, lemurs and crocodiles well North of the Arctic and South of the Antarctic circles.
you’d pop in and the first question would be:
Who turned off the heat? What’s this white stull at the top and bottom?
In previous visits many times ago, you would have witnesses snowball Earth but a only a couple of times—a cold Earth is a rare Earth.
It is what it is, no? Mankind is after all, a product of the Earth, and any affect mankind has on the Earth is, well, part of the Earth!
That is a way of looking at it that I have never considered! Very effective.
