Eliminative Materialism
it is just an idea, a baseless rather absurd. The actual world is a reality. we experience it all the time. When one throws a ball in the air and the other catch it. it is a common experience of reality.
It’s a misconception that science has proven anything in this regard. Eliminative materialism is just one of the many hypothetical claims. Some of these ideas in the field of philosophy of mind are packaged as science and cause confusion for the common people who do not understand the academic debate at a deeper level.
