If Aliens visited us in the ancient past, then what evidence did they leave?
A question that is asked often!
Here is some artefacts that have mysterious origins:
The Sri Lanka Meteorite Fossils
Researchers who analyzed the remains of a meteorite that fell in Sri Lanka found that their subject was something more than just pieces of space rock. It was an alien artifact in the most literal sense: an artifact made of actual aliens. Two separate studies have found that the meteorite contains fossils and algae that are clearly of extraterrestrial origin.
Professor Chandra Wickramasinghe, the leading researcher on the first study, says the fossils provide compelling evidence of panspermia (the hypothesis that life exists throughout the Universe and is spread by meteorites and other solid space debris). However, he is not without his critics. Wickramasinghe just happens to be a noted panspermia enthusiast with a tendency to claim that almost everything is of extraterrestrial origin. What’s more, the traces of life the meteorite contains are actually freshwater species commonly found on Earth, which seems to indicate the object has been contaminated during its time on our planet.
A Russian man found a strange piece of machinery from Vladivostok, the administrative capital of the Primorsky Krai area. The object resembled a piece of tooth wheel and was embedded in a piece of coal he was using to light a fire. Although discarded pieces of old machines are not uncommon in Russia, the man became curious and showed his find to some scientists. Testing revealed that the toothed object was almost pure aluminum and almost certainly artificially made.
Also, it was 300 million years old. This raised some interesting questions, as aluminum of this purity and shape can’t form naturally and humans didn’t figure out how to make it until 1825. Curiously, the object also resembles parts that are used in microscopes and other delicate technical devices.
Although conspiracy theorists have been quick to declare the find a part of an alien spaceship, the scientists researching it are not willing to jump to conclusions and wish to run further tests in order to learn more about the mysterious artifact.
Incas and other pre-Columbian people left behind some extremely puzzling trinkets. Some of the strangest are probably the so-called Ancient Aeroplanes, which are small, golden figures that closely resemble modern jet planes. Originally thought to be zoomorphic (meant to resemble animals), the statues were soon found to have features that look very much like fighter planes’ wings, stabilizing tails, and even landing gears. They were aerodynamic enough that when ancient astronaut believers (allegedly) made model planes with their proportions and fitted them with propellers and (again, allegedly) jet engines, they flew perfectly. All of this has led to speculation that the Incas may have been in contact with (likely extraterrestrial) people who were able to build advanced jet planes, and who perhaps even possessed the technology themselves.
Well, that, or these wonderful statuettes might just be artistic representations of bees, flying fish, or other winged creatures. As always, the beauty is in the eye of the beholder
