"reality doesn't exist, and has never existed. There isn't one reality in the universe, there is one for every living being, and every reality is different. There isn't a single static reality"
Drivel, pure unadultered grade A garbage.
1) If reality didn't exist, we wouldn't exist either.
2) If everyone had their "own" reality, A: We would not be able to communicate with each other, and B: Given that we can communicate (Which we shouldn't be able to do) we should all see the world in a COMPLETELY different way, we patently don't, we all see the sky as blue, we all experience wet-ness with liquids, we all experience a force pulling us towards the ground.
3) Different people would not be able to reproduce the exact same data by replicating an experiment.
4) All the principles and understanding we have of the world would be false, as a result nothing based on them would work, planes, cars, computers, would do nothing.
