The pyramid builders: human or aliens?
The pyramid of CheopsTo keep it "simple", we only use this monument as an example. After all, this pyramid alone is an incredible achievement. But we do not forget that nearly a hundred pyramids in Egypt alone have been cataloged and studied to a greater or lesser extent. Worldwide it is about thousands of pyramids and temples. Despite all theories, for or against, inside or outside the academic world, "believers or" non-believers ", one thing is certain. The pyramid is there. And until we prove the contrary, we have not yet succeeded in making a copy That means that we will never be able to do that - of course not - if we look at the exponential curve of our technological evolution, that chance will only get bigger - it will be a hundred years since we started building planes And some sixty years later, we sent people to the moon, and whoever claimed that in 1913 might have been locked up in a psychiatric institution.
What is the chance that ...? HumanOur current "civilization" is, as is assumed until now, a historical evolution in about eight thousand years (although that boundary is slowly shifting, see eg Göbekli Tepe). However, our technological achievements are a true explosion of the last two centuries in particular. But even the last ten thousand years deposited on a timeline of our planet are not visible to the eye. Who says there were no periods in our history with older, even "more civilized" nations? This is of course already a source of intense debate. But is it impossible? We should certainly not underestimate human ingenuity. Man has already proven to be capable of a great deal, both in a positive sense and, unfortunately, also in a negative sense.
What is the chance that ...? "Aliens"As far as we know, there are nine planets in our solar system. On one of these, humans have developed as a form of life.
Statistically, the outcome is very high. Statistics are not proofs, but describe chance or opportunities. To put it in a plastic way: "There are lies, there are blatant lies, and there are statistics." A possibility inherently does not exclude impossibility. That being said, we focused on the universe. There are billions of galaxies. Our own galaxy counts billions of stars. It is likely that other galaxies also have billions of stars. And how many of those stars have planets? Our own sun has nine. Impossible to say how many planets there are. For the sake of discussion, let's assume that there is one planet for each star and there are one billion galaxies with three billion stars. Then there are 3 billion² planets. Suppose the chance of living on a planet is one millionth. Then there are 300 million planets with life. Suppose that the chance that "a human species" develops on a planet is also one millionth, there are 300 planets with human civilization. The chance that a civilization is older, younger or equal to ours is one in three. That leaves 100 civilizations that can be in a more advanced stage. If we see what we have achieved in five thousand years, what is possible in 50,000 or 500,000 years? Again, this is not proof, it only represents a statistical possibility, but one that is based on a very low number of stars. After all, we do not know how far the universe goes.
How certain is certain?Are there any aliens here on earth, or have they ever been there? The answer depends on who you ask the question to.
We have taken our first steps into space ourselves. Who knows where we can go in a thousand years? Our imagination evolves irrevocably with our knowledge and ability. Few can imagine that we can travel to another solar system in the foreseeable future. But in 1800 nobody could imagine that we could travel to the moon. When the Spaniards invaded Mexico in the early 16th century, they were considered gods by the Aztecs. Who knows, we might invade another planet in a thousand years. Perhaps "primitive cultures" ask the same questions about us. Maybe they will argue about it as much as we do or make someone who asks questions just as ridiculous as we still do with so many. In our world, asking questions takes courage; especially if those questions are about what we believe or accept as "truth."
Of all the probabilities, truth is the least likely.
