(5,963 posts)Not to mention your own amount of hyperbole on display in your first paragraph.
The more we understand about life and where it can form and survive, the far more likely it is that it has formed in other places of the universe. MANY other places most likely. Given that, there is also a strong probability that other intelligent life has also developed in other parts of the universe.
Now you seem to think that simply because we haven't heard anything from them yet that it is a slam dunk that there is no other intelligent life out there. Given the extremely small amount of time we've even been listening, as well as the small amount of space we can listen too at any given point, as well as how unlikely it is that a signal would both be strong enough to get here and still be deciphered AND that there would be nothing between us and the source to garble it, and assuming that they didn't devise a different form of long range communication that worked outside of the electromagnetic spectrum (something dealing with quantum entanglement for instance) thus causing them to only use the EM spectrum for a short period of time, how you can honestly make such an assertion and still call it even remotely scientific is simply beyond me.
That's not to say that it isn't worth listening (because its all we can do right now), but you are drawing a completely ridiculous conclusion from the available data.
