If you don't know what is the simulation theory, it is defined by Wikipedia as:
... the proposition that all of reality, including the Earth and the universe, is in fact an artificial simulation, most likely a computer simulation.
People like Elon Musk believe we are living in a simulation https://www.nbcnews.com/mach/science/what-simulation-hypothesis-why-some-think-life-simulated-reality-ncna913926
And big institutions such as Bank of America have started to ponder about this possibility. They gave it between 20-50% of probability that we are living in a simulation. https://www.businessinsider.com/bank-of-america-thinks-theres-a-50-chance-we-live-in-a-matrix-2016-9
