Water Trapped For 1.5 Billion Years Could Hold Ancient Life


This map, from the United States Geological Survey, shows the age of bedrock in different regions of North America. Scientists found ancient water in bedrock north of Lake Superior. This region, colored red, was formed more than 2.5 billion years ago.

Wow! This is so cool! I can't believe that 1.5 billion-year-old water could hold 1.5 billion-year-old microbes. Anyway, I read some of the comments on the site, and one person said that the microbes probably evolved the same way. I don't think so. First of all, they were never exposed to oxygen. Second of all, they were never exposed to light. I think there could be some really cool life forms down there!!!

I completely agree with Sammie. I can't believe that 1.5 billion-year old water could hold 1.5 billion-year old microbes either! This is information that can lead to the secrets of the earth. Congrats all the scientists ;)
I am kind of confused. I wish this article would have explained the concept of these microbes and everything more thoroughly. Over all I rate this article a B+.
