Ask HN: Is there any credible evidence for ET intelligent life?
A better question might be, &quot;if there was incontrovertible evidence of the existence of ET intelligent life, how would the conditions of human civilization on planet Earth be different?&quot;<p>Suppose that Planet Earth is actually being visited regularly by ETs with technology vastly more advanced than our own. Our transportation technology runs on the laws of thermodynamics, while theirs would presumably be powered by the more-fundamental laws that govern &quot;dark energy&quot; (superseding thermodynamics, just like Einstein &gt; Newton).<p>I don&#x27;t have any evidence either way, but I think it&#x27;s hubris to make a case that ours is the only planet with life anything like our own, and that equivalents to humanity&#x27;s 1st generation space technologies (radios, rockets, etc) would still be used by more advanced civilizations.
