How would you know?

Because the laws of nature are universal, and these are physically hard problems for us.

Hard isn't the same thing as impossible.

Yes, I don't think the laws of phyics are repealed for anyone. If these supposed "space beings" were to travel from another galaxy, they would be about 2,000,000 light years away. People seem to think traversing a distance like this is as easy as a trip to grandma's house. It isn't. One can't make that type of journey by physics, or any other known form of aerodynamics. I don't think the human mind is capable of truly understanding how vast space really is.

[Quix]

To say that the laws of physics are universal

would seem to me to presume

that our perspective; even our context from which we perceive

somehow includes all that is in all respects for all times in all dimensions etc.

I think that's a rather arrogantly smug and silly ASSUMPTION.
