    Finding alien life on a distant planet would be amazing news - or would it? If we are not the only intelligent life in the universe, this probably means our days are numbered and doom is certain.

            @Nabarup Ghosh Because every time someone goes back in time to a certain point in the past, a new time-branch is created at that point, that leads to a new time continuum i.e sort of a new parallel universe, so the original version of yourself doesn't see the time-travelers, only your new version does, in the new time continuum. The fact that we haven't see them, is because most likely we are on the original time continuum! OR, if we are not on the original time continuum they have visited us, but under cover due to the laws preventing them from interfering too much. One thing is certain: even if they cannot visit us on the original time continuum, they can see us with TV-like devices (like in the movie Deja Vu (2006) with Denzel Washington).

                        Some advice for Kurzgesagt writers: When writing about quite speculative topics, use less certain language.

                                Maybe there is an intergalactic organization regulating how planetary systems can interact with others. Maybe one of their rules is not to interfere with less advanced civilizations. It is just as we don't interfere with those tribal people living in the Amazon.

                                        If such filter exist how do you know that ALL civilizations agree with this? If Such thing existed how do you know that no one ever put an stop to it, and that the reason whe hadn't been contacted is because someone made it illegal in order to it never happen again?

                                          If the Great Filter exists it would definitely be behind us. If the great Filter was ahead of us then their would be other planetary species that we could observe. Personally I believe there is no filter, I think the monstrous size of the universe limits what we can and can not see. Even if human could travel at the speed of light we could really only travel 40ish light years in any direction. That isn't very far...

                                            It's in our nature to reach out. It's not necessarily in the nature of other life to reach out.

                                                          Since we already have so many structures and evidence of our existence send out into space (satellites, space stations, ships but also artefacts like the disc with mathematical information about earth) it would be likely if there would have been millions of other life forms before us that we would have found something similar

I'm supposed to believe that humans and other life forms used logic that we created during our evolution to program ourselves with code so complex that we still do not fully understand ourselves or the world around us. There is no design or program without an engineer. I do not subscribe to religion, but I am also not naive enough to believe that intricately designed and complex creations create themselves. Oh and then I'm supposed to believe that simply because we cannot detect other intelligent life, it doesn't exist. Nevermind the limitations of our technology to detect life in other far-reaching parts of the universe. Yes, let's continue to allow the scientific and medical communities to do our thinking for us, disregarding any agendas they might have. Let's continue walking blindly into the future of gmo's, toxic cancer treatment, addictive prescription medication, air pollution, water pollution, factory farming, forest clearing practices because hey...they know what's best, right?

It instead represents the cumulative impact of eons of chemical reactions whereby elements combined and recombined countless times to form increasingly complex structures. Add to that the likelihood of Panspermia as we have ample evidence of interstellar bodies pummeling the Earth over those eons - bringing things with them from other planets and Stars = to add to the mix. So things rarely "just happen" and facile attempts to characterize them as such undermines all such arguments. The Universe is infinitely complex. Have a nice day.

We're depleting and fighting over resources, we're starting runaway chain reactions in the climate. It's highly probably that every intelligent civilization gets to these problems. If we don't solve the climate problem VERY SOON, we're on the best way to make the planet uninhabitable. And the bad news is, we're not even remotely close to solving the climate problem. Say hi to the great filter! It's coming very soon, you and me might see it live in action.

Structures on the surface most likely collapse, decay, and erode into nothing in time. Structure in space may drift off or deorbit in such time periods as well. To find ruins to gauge how close we are to the filter may not be so reliable. There could be no ruins, or almost every world we see as habitable could've have a civilization like ours, only to leave no obvious trace.

What's to say that our process to become multi-cellular beings isn't completely foreign to how it is accomplished on other planets for instance? "it's in the nature of life as we know it to reach out" Yeah, emphasis on "as we know it" and the whole "it's very likely that this is a universal principal for civilizations no matter where they're from" but is it a fact? No. Not every human civilization was like Britain stealing everybody else's islands and I imagine alien life would similarly have this variety. You mention that big brains might be rare because they can be useless to survive and they take up too much energy. Maybe the very way that our life spreads is similar and Earth did it the hard/inconvenient way in this instance too. What I'm trying to say is that the very nature of how our life thrives could be well, alien, to how the potential other lifeforms are. Our ability to see into space is so very limited that it wouldn't be too hard for another advanced species to hide from us and while it makes logical sense to Earth life to spread to be as big and all encompassing as it possibly can, that might not be true for others. We evolved to be competitive, but I don't think that's inherent to all potential life. I think another very probable theory is that we are being actively prevented from finding other life. There might be a species so far advanced beyond us that we can't see them intentionally making it appear to us that the filter is there in order to isolate us from other life. Why? Who knows. We could be a laughing stock to a race of beings made out of a type of matter we can't even detect yet. Wanting to feel like we are special is a very human trait. That we're either the first to get where we are or we're the only ones to make it through. Maybe we just don't have the means to search far enough yet?

Survival is the key of a civilization 2. Civilizations need to expand 3. When two civilizations meet, they don’t know whether each other will attack or befriend 4. The risk of attack is more likely because civilizations wished to expand, and finding a planet that can provide life is good news because it means that planet can be colonized 5. because of the risk of being discovered and attacked when meeting another civilization that is more advanced, civilizations must not risk being found or discovered 6. Therefore, civilizations are hiding, and the earth not advanced to understand the universal laws above
