The observable universe is a big place that has been around for more than 13 billion years. Up to two trillion galaxies made up of something like 20,000 billion billion stars surround our home galaxy. In the milky way alone scientists assume there are some 40 billion earth like planets in the habitable zone of their stars. When we look at these numbers it is hard to imagine that there is nobody else out there.

    It is interesting that he considers humans to be advanced compared to ants and ants advanced compared to bacteria since bacteria are more powerful than ants and ants are more powerful than humans. There is one category in which humans are far ahead of ants and bacteria: arrogance.

    Maybe we don't see signs of Type 2+ civilizations because these civilizations learned and understand the importance of conservation and the harmful effects of artificial influence on nature. They're taking explicit steps to avoid catastrophic events by making sure their presence doesn't disturb anything beyond what's necessary.

    It's all relative, we might be omega civilization and our cell cores are just universes. Our universe might just be a cell core of another organism.
    we might be omega civilization since we create bacteria/viruses in labs. We might be just a bacteria created by another species in the lab.
    also we create virtual world like in pc games. We might just be a pc game for another species.

    A type three civilization could easily be right in our midst or even actively interacting with or controlling us and we would never know. A more advanced civilization than our own might not just be more powerful, but also more subtle. Who says they need megastructures? They may have figured out far less invasive ways of getting their energy fix or may have outgrown the need for material expansion such that they leave a very faint footprint.
    Perhaps they know about us already and have intentionally distorted the information we have access to from Earth for our own good.
    This possibilities require more assumptions than supposing that all alien civilizations are space capitalists, but I don't find the assumptions very compelling. I would be more confused (not to mention disappointed) to find that extraterrestrials are like us than not like us.

    I think the reason we haven't discovered other species yet is because of the fact that any radiowaves or light takes time to travel and over time becomes dated meaning in basic terms we see the universe around us as it was in the past which means by the standards provided here we would not see another civilization in our solar system yet.

    Here's a theory: All the greater celestial bodies in the universe could be considered Gods, except they're not intelligent at all - they're just unfathomably energetic and chaotic. Moreover, we are to the greatest celestial bodies what they are to galaxies what they are to the entire universe.
    Being able to have control on such a seemingly infinite scale would require us to not only theorize that we can bypass the laws of physics as we know them, but also have the means to do so. That would require an intelligence so evolved that we could actually comprehend the concepts of the different plane of physics at our disposal. Not only that, but we would have to physically evolve into something equally as uncomprehensive.

    Humanity likes to protect its ideals. In a country, for example, states argue, but when the country goes against another country, the entire country fights together. If we encounter another civilization, we'd forget all our arguments, and work together as one. Probably.

    Contact with other intelligent civilizations is next to impossible due to the vast distances involved. Our own galaxy is about 100,000 light years across, but even if our closest neighbors were "only" 100 light years away, it would take 100 years for just a message to reach them, then another 10 decades to get a reply. And unless they can travel faster than light speed, they wouldn't get here for thousands of years. FYI, in just one year, light travels roughly 6 trillion miles! And if there's intelligent life on the other side of our galaxy, you would have to multiply 6 trillion by 100,000! And that isn't taking into consideration all the billions if not trillions of other galaxies, which are moving away from each other constantly as space continues to expand. So yeah, there may be millions or untold trillions of other intelligent civilizations scattered throughout the universe that we will never, ever know about.
