Some scientists and some non-scientists like to imagine that there are a million planets harboring intelligent life forms, more intelligent than us. What about THAT? Let’s do the Math.* If you spread these one million planet civilizations evenly or randomly across our observable universe, what you get is one planet civilization 200,000,000 light years away from its closest neighbor. Two hundred million light years away from each other! We can barely detect these civilizations’ galaxies with our best telescopes, and what we can see happened 200 million years ago, so even radio communication is out of the question.
So, don’t get up your hopes, next thing you know … will be a … hoax.
* Doing the Math: The Volume of the observable Universe is 8 * 1030 cubic Light Years. One of those one million chunks would occupy a Volume of 8 * 1024 cubic Light Years, a cube with a dimension of 2 * 108 cubic Light Years on a side, or 200 million Light Years on a side. The average such cube would contain more than 100,000 galaxies, so one civilization every 100,000 galaxies! Not too brimming with intelligence, eh? But the likelihood that we are IT is even more remote.

The genus Homo appeared on planet Earth about 2.5 million years ago, the species Homo Sapiens appeared roughly 800,000 years ago, and the subspecies Homo Sapiens Sapiens (double-wise? Hah!) (that’s US, modern humans) about 200,000 years ago (as I am no paleoanthropologist, I can be excused for mis-stating the dates, but that does not affect my argument). We modern humans traded hunting and gathering for the domestication of animals and agriculture a mere 12,000 years ago. The Industrial Revolution (beginning with steam power) began less than 300 years ago, and the wide-spread use of electricity took place over decades from the late 1880’s through the Great Depression (still on-going in many places in the world). Before that transformative transition, all of your ancestors knew what the Milky Way* was and they could see it every night. The advent of Cell Phone technology in the 1990’s and of “Smart Phones” (Blackberry, iPhone and Android) in the last decade signified the last nail in the coffin of our being able to differentiate work from play and rest, and our entire dependency on Industry, Electricity and Technology. When you go on vacation today, even if you spend it on Tahiti; do you really go on vacation, are you really isolated in any real sense from your workaday world? What is the difference between you and a robot that mimics you? Today, we know the difference, but the tomorrow when we won't see the difference is not that far in the future.
