1. Quantum Mechanics - if you study the double slit experiment and the delayed choice quantum eraser experiment, the only way to explain the phenomena that results from those experiments is to assume we live in a computer generated reality.
2. Mandela Effect - I along with millions of other people have memories of a reality that no longer exists in this reality and presumably never existed. From the Berenstein/Berenstain phenomena to the changes in the location of continents like Australia on the world map, I have memories of a reality that has now been changed. Only way to explain this phenomena is if we live in a computer simulated reality that has been modified.
I used to believe we lived in a computer simulated reality because of quantum mechanics alone. But since December 2016 when I discovered the Mandela Effect, I now know we live in a computer simulation because I have experienced a change to the Matrix.
