Researchers Say Oldest Glaciers Are 2.9 Billion Years Old

World’s oldest glaciers are around 2.9 billion years old, according to new research. It might be nearly impossible to accurately predict what our earth would look like billions of years ago, but the new study could fill some of the gaps regarding the geology. Evidence presented in the study suggested that the oldest glaciers used to be in South Africa, when our earth was like a snowball.
