Aliens are real

Refering to point 3 of my previous argument: 3) Aliens can exist without interacting with humans. Everyone constantly seems to think that aliens need to be humanoid or have extremely advaced technology in order to exist, but honestly that is not necesary. Aliens may live billions of lightyears away still in their version of the Jurassic Era and they still would exist. Saying "aliens can't exist because all sightings were false" does not mean that aliens do not exist: it only debunks the alleged 'sightings'. There might be real aliens out there wondering if there are other planets with life on them as well, the same way we wonder about it. Aliens do not, in fact, have to have existed for millions of years before us. They might not have advanced technology as us, maybe they're in their own version of the Stone Age. Maybe the alien species is more like dogs; they might not be as intelligent as us, or they might not possess a form which allows them to do complex task, or even think of doing complex tasks. Alien fauna might be less or more advanced than us, but there is no need for them to actually interact with us. Like how Mt. Everest has always been the world's tallest mountain even before being discovered, aliens can exist without us ever seeing them. Extraterrestrial life definitley exists outside of our solar system, most likely outside of our galaxy, and might even be on the opposite side of the universe. Considering that the laws of physics can be universally applied, it is unlikely that a species has developed a spacecraft capable of supporting life for BILLIONS of lightyears, excluding the fact that they would need nourishment when they did not have access to planets with ecosystems that support their physical necessities, and would need to find an extremely effective energy source that could fuel the spacecraft. They also would need to achieve light-speed in order to make the journey in as little as several billions of years. They might use light from the surrounding stars as energy, but there's a limit to how fast they can move. Perhaps there's a legion of aliens coming our way, but they have not gotten here yet. As for the "If a species is 1 million years more advanced than us then they'd be all over the galaxy and possibly the universe" argument, the species might have simply wanted a new set of planets to settle on. Finding those planets, they might have chosen to stay there and not colonize the rest of the universe. Not every extraterrestrial species is going to be the Europe of the universe. Furthermore, the species might be non-violent, have morals and ethics that we humans are incapable of comprehending, or something similarly mind boggling. As such, they may have no desire to counquer other planets or meet new civilizations. For all we know, they might be observing everything in order to learn about us, or use us for entertainment. In short (kind of) 1) Alien species might be younger than us and be less advanced. As such, there is a chance that they're in the Jurassic Stage, are still their world's equivalent of apes, or are medieval-version humans who simply did not know a single damn about the universe. 2) Even if alien species were to a million years more advanced than us, they might be too far from us to be able to do anything, might have morals and/or ethics that make them uninterested in doing anything, or they simply are observing us without interaction. 3) Not interacting with aliens =/= Nonexistence of aliens. New species are discovered on Earth every single day and yet that does not mean that the species has been magically poofed into existence by Scientist McScience who just so happened to imagine it. An undiscovered species still exists, it simply is not discovered by the humans. Side note: Thank you for picking up this debate!! It's my first debate here, and I am very happy it got responded to so soon. Have a great day Karar!
