To start, the primary argument is that the odds dictate that if we ever do come in to contact with ET life they'd either be considerably more
advanced than us, or considerably less advanced. The odds of life coming into contact with each other at all is arguably low [so far as we know], so
the odds that the two lifeforms are similarly advanced [of similar age and evolutionary destinations] is exceedingly unlikely. Unless there is life
within our solar system, interstellar travel is imperative... and there are obvious problems with interstellar travel. Just consider what the odds
must be of two comparably advanced civilizations meeting are. Consider the vastness of space, and the expanse of time. The odds of being in the right
place, and right time, are incredibly low. Of all the star systems, over billions of years.
Look at us as an example. We're only a few thousand years into any sort of civilization. Only a hundred or so years into electricity. Only in the
last half decade have we left our planet... and only to our own moon. We might be gone in another thousand years, or ten thousand years. Even if we
survive another 10'000 years, we have to assume that other life exists and has the ability to reach us [or for us to reach them at some point in the
future] and for us both to be similarly advanced. We've been around for 200'000-400'000 years or so, and only for the last 100 years have we been
able to fly.
Just try and consider all these things. The number of galaxies, and their distance from each other, as well as how old the universe is. Two
civilizations separated by 100'000'000 years is the blink of an eye to the universe. Two civilizations separated by 10'000'000 light years is a
speck of dust in the universe. So, as long as we rely purely of theory and statistics, we have to assume two things. One, that there is definitely
other life out there. And two, that the odds of us finding any significantly advanced life [or them finding us] is statistically improbable.
