We can't be entirely certain of anything, but the bolded stands out. You're giving yourself wiggle-room. Why would alien brains allow psi-powers while human brains don't? Are you opening the door to the existence of psi powers in possible non-humans? What about psi abilities present in possible advanced machine intelligences?
It seemed obvious to me, but I'll spell it out for you as you've clearly misunderstood, and attempted to insert your own snark into my post.
We can only measure what interects with particles here on earth, because we live here on earth. If there are telepathic aliens out there, the effect of their ability would not be measurable because it is too far away.
