We are evolving here and are part of this nature
We are very fragile creatures and are very specific captives of our environment. (Stop the world. I want to get off)
To destroy us would be a very simple matter for a race of beings with a technology of interstellar travel.
How can our existence benefit them? Assuming their interaction with us over the millinear is as reported or similar to the stone carvings and ongoing reports, arrond the world.
There is just too much of it to dismiss it all as fantasy
Chaos theory shows that the ratio of chaos to order is 4.6692 : 1. this roughly translates to the 80: 20 rule. Which means that we only perceive 20% of reality. The other 80% is chaotic and beyond our primative perception.
Imagine, Imagine.
