What makes you think humans are smart enough to know the differenre?

Assuming they use a Dyson Sphere.

Assuming they use a Dyson Sphere.

Why do you assume a Dyson Sphere is the only way for a civilization to get
lots of energy?  For all we know, they've figured out a way to harness
energy that causes the expansion of the universe.  Or, idk they made
themselves a small black hole and throw planets into it and collect Hawking
radiation and use lasers to send the the energy back to their planet.

What I'm proposing specifically may be ridiculous, but I think it stands
pretty clearly that we have no way of knowing whether ET use some kind of
energy collection method that we do not yet have a physics framework for.
