Just like the classic road sign that used to be on I-5 between Los Angeles and the Mexican border.

Abstract
The goal of the search for extraterrestrial intelligence (SETI) is to quantify the prevalence of technological life beyond Earth via their ‘technosignatures’. One theorized technosignature is narrowband Doppler drifting radio signals. The principal challenge in conducting SETI in the radio domain is developing a generalized technique to reject human radiofrequency interference. Here we present a comprehensive deep-learning-based technosignature search on 820 stellar targets from the Hipparcos catalogue, totalling over 480 h of on-sky data taken with the Robert C. Byrd Green Bank Telescope as part of the Breakthrough Listen initiative. We implement a novel β-convolutional variational autoencoder to identify technosignature candidates in a semi-unsupervised manner while keeping the false-positive rate manageably low, reducing the number of candidate signals by approximately two orders of magnitude compared with previous analyses on the same dataset. Our work also returned eight promising extraterrestrial intelligence signals of interest not previously identified. Re-observations on these targets have so far not resulted in re-detections of signals with similar morphology. This machine-learning approach presents itself as a leading solution in accelerating SETI and other transient research into the age of data-driven astronomy.

+1 yDo I believe in aliens yes and no no because science says there's no solid evidence that aliens exist and because no other planets in the solar system can support life and yes because maybe if there are aliens out there the conditions aliens need to survive are different than humans

So I don't have any idea how possible. I can say that, if there is life on other planets, it's less likely to be multicellular organisms.
10 Reply2.2K opinions shared on Other topic. Do I believe that there is life on other planets, yes absolutely.
Do I believe that that life is intelligent, probably
Do I believe that this life has visited earth, I'm highly skeptical.
11 Replyabsolutely. It seems impossible that there wouldn't be aliens if you look into how big this freaking universe is. Surely there are other planets just like earth out there, probably many trillions. The weird thing about it is why aren't they here? they must be avoiding earth for some reason.

+1 yIt's impossible for them to not be real. With the literally billions of planets in our own galaxy, life as to have evolved in more than one place. Weather or not they are visiting us though is debatable, mostly because we are still a violent primative species.

Hey for shits and giggles I looked more into this topic.
Here is something very cool about a secret space program on YouTube.
