    Yah, but it’s also statistically more likely that we have missed crossing paths with them or even seeing their signs by millions of light years, as well as millions of years of history.

    Entire empires could have risen to galactic power and ruled vast portions of the galaxy and finally splintered, evolved or gone extinct in just the million years before humans invented stone tools. Or some thousands of years during the Devonian period or something. Or the nearest planet with life is still just boneless fish and will need a hundred million more years to develop radio.

    We’re not only a microscopic dot in space, we’re also a microscopic dot in time. And our ability to even look out into space and detect anything is a tiny shaving of time off that dot.

      As far as the history of the universe is concerned we are actually super early on in its lifespan. So in some ways it’s actually more likely that we will be one of the early civilizations that perish before the others show up.

      The problem is the human mind cannot understand the concept of how far one single light year is. Even Fermi struggled.
