Scientists Discover the Oldest Fossil Yet
Science may have just taken a big step forward as a team of researchers have now made known the four year-old discovery of a certain fossil, which they're now confident is 3.7 billion years old. That's less than a billion years younger than the time that Earth is said to have formed, 4.6 billion years ago, and 220 million years older than the fossils previously regarded to be the world's most ancient.

Some scientists are skeptical about the news, as the Earth's conditions would have been hellish and inhospitable 3.7 billion years ago. However, the fossils that were retrieved from Issua in Greenland have certain formations which are apparently indicators of microscopic organisms known as stromatolites.

If the new date proves true, then it could mean that life is able to survive in harsher conditions than previously believed, and thus the chance of life existing on other less hospitable worlds, such as Mars, becomes a great deal larger.
