Some of the oldest rocks in the world have some of the oldest signs of life.
Oldest fossils of life going back 3.5 billion years ago. It's cool and all but I was thinking and went off on a tangent. I think it's really cool that we have 3.5 billion year old rocks. Australia is about the only place with them because it's been a pretty consistent land mass over the history of Earth. With the amount of shifting and moving and subduction zones, it seems like sitting there unchanged for 3.5 billion years ~ 3,500,000,000 years is quite a feat. If anybody could do it, rocks could do it. Go rocks! Way to exist.
While really old fossils are cool, my suddenly being impressed by the feats of rocks warranted a blog post.
