I think that animals knowledge its will be 21st century humans.
robot designed themselves
The world have unique currency only one president for earth
All the humans have own spy ships they all traveling on the sky and travelling speed is very high, they rotate the world with in minutes
robots take the all the jobs of humans
underground houses
invented the different type of animals
people have robotic currency system,
population will be less compare to now
humans are taller and look charm
humans miss the ear like a tile
getting the resources from the other planets
