As explained in the video, given a few realistic assumptions there would be a strong mathematical argument for the hypothesis that we are just a simulation.
the mathematical argument would be something like this>
given that the mayority of minds that exist in the universe are artificial minds that live inside a simulation, it is more probable than not that you live inside a simulation, and maybe Aliens simply what to know how would you react if you (a simulated being) would react if you are confronted to this theory.
maybe you are just part of a betting site in some alien world and aliens are betting on whether fi you will accept or reject the simulation hypothesis after watching the video
Assumptions
1 There is intelligent life in other planets and/or in other universes, with enough technology to create simulated worlds with intelligent minds in it, where these minds are not aware that they are part of a simulation
2 some of these intelligent beings have the willingness to create billions and billions of these simulated worlds
none of these assumptions has been proven but most people would grant that these assumptions are at least possible. So as long as you consider these assumptions realistic and probably true, you would have to consider seriously the idea that you live inside a simulation.
assumption 1, the idea of other intelligent life that is much more intelligent than human doesn't not seem to be an unrealistic assumption.
assumption 2 we create simulations all the time, ether for entertainment, or for something useful like predicting the climate, so why wouldn't intelligent Aliens create simulations with intelligent minds in it for similar reasons.
