These aliens were able to access the most advanced technology and would start nuclear wars on our planet.
This is why primordial global warming occurred as they were farming the Earth’s nucleus in order to power up everything. This caused the Earth’s core to melt down and its poles to go along with it.
As you may have guessed by now, the planet didn’t take it all so well, so before we knew it, we were completely on fire, literally. The planet was hot enough that life couldn’t be sustained. These 60 million year old creatures decided to leave our planet and seek out another home.
We took over after they left and, since we weren’t technologically advanced, had no intention of harming the planet. Instead, we helped it heal, we lived in the forest and we lived off of nature’s mercy. This is the truth that you won’t find in any history book, it is the real truth.
