The Ancient Invisible
There are bacteria buried deep in the sediment at the bottom of the ocean that produce methane. Nobody knows how long they live. It could be thousands of years or even much longer. They are frozen in methane and are spewed forth out of mud volcanoes only to fall back under the ocean and restart the process again. They could be as old as mountains and older than the oldest trees.
