In order to explore our solar system, we need to be a Type 1 Civilization. In order to explore our Galaxy, we need to be a Type 2 Civilization, and so on and so on. So you can see how much energy is (hypothetically) needed to be able to freely control, colonize, and habitat certain areas of space. Again, this is an estimate and hypothetical.

With even sub-light technology that is possible with our current technological and scientific understanding, then it would only take from 5 million to 50 million years to colonize the galaxy (hypothetically). The Milky Way is estimated to be almost as old as the Universe; 13.2 billion years old, while the universe is only 13.7 billions years old. That's enough time for the Galaxy to be colonized 2,600 to 260 separate times based on time scale alone (basically, not including the fact that you could have two civilizations attempting to colonize at the same time, within a few million years of each, etc).

We have yet to see a shred of evidence that this has ever happened. No Dyson Spheres, no artifacts, no structures, no ships, no probes, no signals, nothing. NOTHING. Again, this is a huge *YET*, as there may be other reasons why we can't detect their signals, their probes, etc. But if you think about this math alone, it makes no sense that we have not seen anything at all even remotely showing that there's another civilization out there. So, what's happening? Are they dying before they get off their home planet? Is there no one else? Have they evolved in a way that we cannot detect/notice?
