    There can be some sort of life by bacteria witch in the many of stars plus planets in our galaxy and all the other galaxies and what's in those space doesn't have an alternative ending space is open to everyone to explore and plus maybe some planets was born even way before and or after our star formed which includes past and future there could be other life forms that was before our life time including the dinosaurs and the first ice age that changed our planet after can

        Has anyone on this thread researched this subject at all? There is overwhelming evidence we are being visited that can easily accessed .

          That is saying that global warming doesn't take over their planet

              “Saying there is no life in the universe because we haven’t found any evidence is like going to the beach and scooping up a glass full of water, and saying ‘there are no whales in this ocean’”-Niel DeGrasse Tyson

                I don’t believe it’s just us but even if it was, are we not literally the universe experiencing itself? Outside of that, I think life outside of us probably looks much different. People tend to conceptualize things in our own image. Even God (like at the beginning of this video). We make aliens out to be human-like. What if it’s not that at all? What if other life is just something we can’t really even comprehend because it’s so unfamiliar? We live in an amazing time but the messed up thing is, everyone dies with these questions unanswered. I always have this thought that when I die, all the great mysteries of everything will be revealed to me....if there is still a me. That would be awesome.

                  Because the distance between planets is just too damn big.

                    Why don't multiple eye-witness accounts, from reliable people, of strange crafts in the sky and unexplained phenomena over the past centuries count as some kind of evidence?

                            There are many reasons why we haven't yet detected intelligent life. 1. Perhaps they haven't reached our level of technology yet. 2. Or they have technology which doesn't give themselfs away just in case species from other worlds are hostile so they remain silent, this could be true if they have had a bad experience with alien contact. 3. Maybe they are not interested in other intelligent life forms. 4. They can't fund the research or the equipments. 5. Their planet doesn't have all the materials that we have for making high tech equipment. 6. It could be their signals haven't reached us yet or ours haven't reached them yet. 7. Maybe they don't have the same curiosity as we do. 8. They have found lots of intelligent life so now they are use to it and also bored with it. or they don't care anymore. 9. They are signaling with high technology but we're just not using the correct detectors. 10. Maybe they are signaling out into space with high technology in the hope they reach others with the same technology and are not interested in us yet as we haven't reached their level of technology for them to be interested in us. 11 Maybe they unintentionally distroyed themselves with some kind of experiment which could be the filter that we need to avoid. Or some other natural or alien made disaster such as global warming. 12. Maybe they are scared to make themselfs known. 13. Maybe they are highly intelligent as we are or even more but they have dolphins or elephant bodies or some other creature unlike human form where such physical form might not allow them to advance technological or even very much scientifically. 14. They know what we're like so they don't let us know they are here until we advance enough not to kill each other or try to harm them. 15. Maybe their religion forbids contacting other intelligent life forms. 16. They've shrunk themselfs to a tiny size to avoid environmental damage or detection so their equipment may not be powerful enough to reach us, or shrunk themselfs to avoid overpopulation. 17. They time traveled and accidently made themselfs extinct. 18. They don't believe in aliens so they don't bother looking. 19. They got taken over by AI robots that they created. 20. They downloaded their consiouness to a robot or machine now they are stuck there or they are just happy there and don't feel a need to search for other beings. 21. They are looking for life forms known to themselfs of which they are so different to us that they might not recognise us as being life. 22. Maybe no technology exist to travel fast enough to reach other stars so they think space is too big and it'll take too long to travel to other worlds. 22. They already checked earth out years ago perhaps during the dinosaur era and didn't find intelligent life, or the dinosaurs terrified them away. 23. They saw us in our primitive or ancient times so left us to it. 24. They zoomed in from their planet with their high tech telescopes and seen earth as it was before humans came along. 25. They transformed to a higher density invisible to physical forms. 26. They raised their consiouness, now they are in a higher state of existence like being spiritual beings. 27. They might already be here. 28. We might be them who came from another world to be left here to colonise earth, and we don't know we're them because it has been forgotten for some reason. 29. They don't want to intervene. 30.
                            31. Maybe they found lots of planets but realised they can't teraform them or it takes way too long so they don't bother. 32. We're alone. I'm sure you all can think of more and better reasons.

                              Maybe that once intelligent beings reach a high level of technology they unintentionally distroy themselves through an experiment that they carry out, each intelligent civilisation not realising that the experiment they are about to carry out creates so much energy it completely distroys them. So this could be the filter. Maybe we should be more careful when spashing particles together or carrying out other experiments that could potentially be dangerous.

                                        Can a species advance enough to space travel before destroying their own planet and them selfs with it that’s the question! I think not this is why we don’t find other live

                                          In fact if we met any of the aliens , they might destroy our universe entirely, it's better, we should not disturb them, also same thinking by physist Mr. Stephen Hawking. More fully our technology and science is too far behind aliens technology, either we saw them nor proof of aliens photos.

                                            It might be because since they are so far away it might take the information and light made by them arrive here light years. This could mean that we are seeing their planet before they grow.

                                                      Two things to consider: 1) the age of the universe has been revised down to 11 billion years old. If the Earth is 4 billion years old, that's almost half universe's age for the Earth to form, cool, get a moon to stabilize it, collect water, and ensure its magnetic field is strong enough to filter out harmful rays from the sun. Then the dinosaurs would have to all die before any mammals can start taking over.
                                                      2) The early universe would have been too harsh for all or any of 1) to take place so if there is another form of life out there with intelligence, it would have to be no more advanced than ours. Since we don't yet have the technology or the knowledge to communicate with extraterrestrial life, so won't other life out there with us.
