Always wondered about that.

Even aliens that were here....in our space would be so advanced. Why would govt or MIB even try? People can't grasp the power differential. Make movies like Independence Day.

Nigga, they could fry our planet from across the galaxy.

And outside this dimension? Godlike power isn't sufficient to describe it.

Even the religious route (which I subscribe to) defines reality as a simulation. They arent so far apart.

Unless the voices aren't good, are actively evil and deceiving you.
This must also be considered.

But why would something so massively advanced torture or harm us?

It would be like writing a discourse on harming ants.
