Rumors have been flying since 1947 about aliens from outer space visiting us. There have been reports of Unidentified Flying Objects [UFOs] flying and even persons reporting being abducted, human DNA identifying alien ancestry and more recently extraterrestrials living among us. These reports have raised the possibility of aliens from outer space visiting us. These reports have opened speculation about aliens on a big scale and how civilization began on earth! This article briefly explores all this fascinating mystery and speculation.

NASA by GovernmentAttic.org released a document about UFOs on November 30, 2021 that confirmed that the US government knows about numerous flying objects over the past 20 years. This information is related to the unconfirmed 1947 report of an alien craft that crashed on a farm in Roswell, New Mexico.  Crookes: Roswell incident 2022 Numerous UFO sightings have also been reported but never confirmed by the USA government.

According to Wikipedia, "Alien life, such as microorganisms, has been hypothesized to exist in the Solar System and throughout the universe. This hypothesis relies on the vast size and consistent physical laws of the observable universe. According to this argument, made by scientists such as Carl Sagan and Stephen Hawking, as well as notable personalities such as Winston Churchill, it would be improbable for life not to exist somewhere other than Earth. This argument is embodied in the Copernican principle, which states that Earth does not occupy a unique position in the Universe, and the mediocrity principle, which states that there is nothing special about life on Earth. The chemistry of life may have begun shortly after the Big Bang, 13.8 billion years ago, during a habitable epoch when the universe was only 10–17 million years old. Life may have emerged independently at many places throughout the universe, as it arose on Earth roughly 4.2 billion years ago through chemical processes. Alternatively, life may have formed less frequently, then spread—by meteoroids, for example — between habitable planets in a process called panspermia. In any case, complex organic molecules may have formed in the protoplanetary disk of dust grains surrounding the Sun before the formation of Earth. According to these studies, this process may occur outside Earth on several planets and moons of the Solar System and on planets of other stars."  Wiki: Extraterrestrials

Avi Loeb speculates that our earth world is easily detectable by extrasolar observers.  Loeb: Universe created in lab 2021 A paper published on June 23, 1921, in Nature, showed that in the past 5,000 years, 1,715 stars have been in the right celestial position to view a populated Earth transiting the sun; with 319 more entering this sweet spot in the next 5,000 years.

Or have we?

According to speculation by Adela Sullman and Paul Goldman, The Unidentified Flying Objects have asked not to publish that they are here, as humanity is not ready yet," Haim Eshed, former head of Israel's Defense Ministry's space directorate, told Israel's Yediot Aharonot newspaper. The interview in Hebrew gained traction after parts were published in English by the Jerusalem Post on December 8, 2020.  Sullman: Israel says extraterrestrials exist 292

In 2020, chairman of the Israel Space Agency Isaac Ben-Israel stated that the probability of detecting life in outer space is "quite large". But he disagrees with his former colleague Haim Eshed who stated that there are contacts between an advanced alien civilization and some of Earth's governments.  Wiki: Extraterrestrials

There is also speculation that many aliens have adopted human hybrid traits and are living among us. But this speculation lacks scientific proof and is probably misinformation. Incidentally, there are hundreds of photos on the internet of persons resembling Homo sapiens that are claimed to be extraterrestrials; but without scientific evidence.

As the scientific community continues to speculate about whether intelligent extraterrestrial life exists on other planets being discovered throughout our vast galaxy, military insiders have come forward to reveal that national governments are hiding a stunning truth. Extraterrestrials who look just like us not only exist throughout the galaxy, but tens of thousands of them have infiltrated communities all over the planet as neighbors, co-workers, teachers, doctors, humanitarians, etc.  Salla: Extraterresrials 2018

The biggest mystery concerning the history of our universe is what happened before the big bang. Where did our universe come from? Now there are a variety of conjectures in the scientific literature for our cosmic origins. MIT cosmologist Alan Guth says “ that the universe emerged out of the collapse of matter in the interior of a black hole. A less explored possibility proposed by Avi Loeb, former chair of the astronomy department at Harvard University and member of President's Council of Advisors on Science and Technology, is of the opinion that our universe may have been created in the laboratory of an advanced technological civilization. An advanced civilization could have developed a technology that created a baby universe out of nothing through quantum tunneling.  Loeb: Universe created in lab 2021

Loeb speculated in a 2021 Scientific American article that our creators may have developed the technology needed to construct “baby universes” capable of producing life.  His theory combines quantum mechanics with gravity that supposedly identifies and recreates all of the universe's ingredients. He also introduced a new classification system for advanced civilizations.

Loeb has devised a framework that breaks advanced civilizations down into classes based on their ability to “reproduce the astrophysical conditions that led to its existence.”

Earthlings would fall into class C because, as a “low-level” technological civilization, we would not be able to recreate our current conditions should the sun suddenly die. He suggests we might even fall into the class D category because we’re actively destroying our only home. On the other hand, class B civilizations are advanced enough to recreate the conditions in which they live, independent of their host star. The possibility that our civilization is not a particularly smart one should not take us by surprise.

We may think we are a smart civilization with all the advanced technology and DNA technology and hopes for improving the world. But inability to control climate change, DNA, viruses, world starvation, political power, wars, violence, racism and the economy are hardly a sign of  an intelligent civilization!

All this alien speculation adds to the mystery of how we Homo sapiens came to exist: Sorochan: DNA is a biological internet that allows intuition, healing, clairvoyance, speech and repair damaged chromosomes 2022

1. The religious story that GOD created life on earth.
2. The evolution theory that mother nature evolved organisms that eventually became humans.
3. The alien theory that aliens visited us millions of years ago or perhaps even more recently and planted the DNA that made us humans.
4. Creation of life on Earth came from outer space.

Take you pick. Aliens may be living in other stars and planets and mixing among us. Knowing who we really are still remains a mystery.
