Is life just a Video game Elon Musk seems to think so. what do you think about this idea. musk and other folks are suggesting that we are entirely simulated beings. We could be nothing more than strings of information manipulated in some gigantic computer, like the characters in a video game. Even are brains are smulated, and are responding to simulated sensory inputs.
The simulation hypothesis proposes that all of reality, including the earth and the universe, is in fact an artificial simulation, most likely a computer simulation. Some versions rely on the development of a simulated reality, a proposed technology that would seem realistic enough to convince its inhabitants. 
Some scientists argue that there are already good reasons to think we are inside a simulation
But this is all just supposition. Could we find any evidence?
