Proof that we are not the first civilization on Earth, and probably not the last
Many artifacts discovered throughout history confirm that we are not the first intelligent civilization on Earth and probably not the last.
Take, for example, the following objects that were discovered in a cave in Klerksdorp, South Africa.
As you can see they are all oddly shaped, some are disc shaped while others are spherical, some are made of metal while others are completely hollowed out.
For the most part they are impossible to explain as they are now over 3 billion years old.
If that's not enough, take a look at this metal vase discovered in the 19th century in Dorchester County, Massachusetts.
It is 500 million years old and is made up of a lot of silver.
The following footprints are as strange as they are supposed to be 500 million years old.
This footprint, on the other hand, was discovered in Nevada by a certain John Reid. They are also about 300 million years old now.
The next artifact looks like another slab of stone, but is actually made of a material even more expensive and difficult to create than diamonds.
It is made of crystalline moissanite grains right here and is hundreds of thousands of years old.
This iron pot is so strange, however, that it dates back 300 million years. It was discovered in 1912 in Oklahoma.
Finally, we have this petrified human finger dating back 100 million years.
