Well if WE humans are real, then whatever we experience, should also be considered real...right?
Because think about it, everything else in this world besides us humans is LESSER in intelligence than us. There are living and non living things, out of all the living things, the creatures, humans are the more intelligent and adaptable ones of its kind. So anything below us, we have the ability to perceive, experience, overpower, and those lesser things and objects AFFECT us and can change our views, our lifestyle, our condition...then it is real.
Well then how do we prove that WE are real?
Well by these simple Latin words. "Cogito Ergo Sum".
Translated in English. "I think, therefore, I am."
We humans are able to THINK and understand things that we find complex or things we want to correlate to. We think to solve problems when we are in difficult or awkward situations. These practices emit 'feelings' and alter our emotions, so when we see these 'effects' being brought forth by ALL of these different types of causes, the EFFECTS that we see and think is the EVIDENCE that we, human beings, exist.
So now that we exist, everything lesser than us (every physical object of this world and universe), exists as well.
We humans are the only creatures or animals, lets say, with free Will.
Now I believe in a creator, a God, and it may not be the same case with some of you, but I am pretty sure that you cannot deny that there is NOTHING else in the universe (as far as our knowledge goes), is more intelligent than us human beings.
And if you try to THINK of something EXISTING that is more intelligent than us, then you are just creating more evidence for yourself that you YOURSELF exist, because you are thinking.
Not necessarily, i am often faced with manufactured or false experience on my path, in fact i would say that a great deal of human experience is unreal. i do believe in a hierarchy of higher intelligence as displayed in nature though, which i think bears similarity to the model you described. However i have not experienced this as a case supporting the reality of our experience, if anything i think that it strengthens the case against accepting our experience at face value. You say that we humans are the only animals with free will, i was wondering if you thought that animals had souls or spirits?
None of our minds are perfect, because we have free-will, we are able to make errors.
Animals, trees, plants, life, etc do have souls, but their souls are not in the state of complete freedom as compared with humans.
ALL animals and other forms of life are under the Will of God.
Can a tree stop producing oxygen? Can a seed refuse to grow its fruit? Can the Sun refuse to shine its light? Can a moon refuse to become a mirror for the Sun? Can the grass refuse to grow? Can the clouds refuse to bring down precipitation?
Of course not.
Everything that God created in this world, somehow, correlates with human beings. All the creations are USED by humans in someway for their benefits.
God created these things FOR us. This entire world is for HUMANS.
God has given humans free will, we have the choice to do whatever we want. How can God test us if HE is controlling us? He cannot, that would be hypocritical.
We exist, there is no denying that. I do not really even know HOW people can deny it, but wherever there is doubt, the truth always can be found.
