Fossils are fascinating things. They’re impressions, that have been left behind by ancient prehistoric creatures and civilizations, to give us a glimpse into what life used to be like on Earth and what inhabited it. In most cases, scientists can decipher what a fossil has to say and make an educated guess on what it means on the grand scale of things. But not every fossil is so easily classified.
Sometimes, we come across something we don’t understand. Whether it’s technology that shouldn’t have existed or evidence of life outside of this planet, some fossils raise more questions than answers.
And they might prove that we’re not alone out there.
