As I mentioned above, how can we trust the human knowledge? How do they know that we are in the world, having a body, experiencing, living etc... ? Whatever we have learn since our birth including the birth and I is the biggest illusion in the first place. Let me give you an example. Phones. If you go back 50 years ago and tell someone cellphone they will tell you wtf is that. So as you see we invented the phone, as our birth, as us, as these/my sentences.
Great deal to learn many stuff. But how do they know?
Knowing is the biggest illusion.
