In case you haven’t heard this theory before let us bring you up to speed. For the most part, experts believe that our civilization didn’t just emerge on this planet after all but that it was the result of thousands of years of evolution on another system altogether.
We originally came from another planet, perhaps another solar system altogether and we moved to Earth in ancient times. This all happened billions of years ago as Earth was still in its diapers.
The theory states that these beings farmed the lands as much as they could and that they ended up causing a sort of primordial global warming, unlike anything that we’ve ever seen before.
This species was forced to abandon Earth around 20,000 years ago though, leaving behind the few that couldn’t be saved anymore. These individuals though didn’t just die off as although they did begin to lose their immortality, they also began to adapt to the Earth more and more.
As time moved on, we began living less and less and we also started to lose our memories regarding the past. We forgot about our past and were only concerned about the future.
What does this mean for us though? It means that the aliens that are currently visiting us are not aliens after all but our ancestors instead. These aliens are catching up on us, seeing how we evolved on this dying planet after all these years.
