Donald Hoffman has a paper supporting the premise that we're in a simulation. There's a number of good youtube video interviews with him. He doesn't seem to be a charlatan, or one of those ancient alien fakes. If they are from another VR headset, or outside our reality, then their "physics" is also different because all laws of science only apply to our reality, (and math, math is universal across all realities, the only constant)... I've heard some surmise it might be easier to transverse universes in a multiverse, (which could be "stacked" like an onion has layers), so they could be coming from there, or they could have been here a very long time, and they're really just living "hidden" on venus, and looking for greener pastures. Could even just be time-travel experiments from ourselves in the future. It doesn't have to be aliens, but it could be... and it probably isn't, and it's still interesting that there's that small chance, which is smaller than us finding it through telescopes, but that chance is still pretty darn cool.
