Is Life On Earth Older Than The Earth Itself?

by Christopher Paul on April 28, 2013

Using Moore’s Law, you can calcualte when transistors were invented. Under a similar logic, scitentists believe life could have began almost ten billion years ago — much older than the Earth itself.

There are quite a few variables to consider, though. Have they factored the correct rate of evolution? Does the notion of the Sun being born out of an earlier star support the idea that life could have formed well before the earth did?

Of course, this may help explain why we haven’t discovered life on other planets:

However, if life takes 10 billion years to evolve to the level of complexity associated with humans, then we may be among the first, if not the first, intelligent civilisation in our galaxy. And this is the reason why when we gaze into space, we do not yet see signs of other intelligent species.
