None of the scientists that are actually working on Abiogenesis, say anything about anything about UFO or spaceships.
Those that have considered extraterrestrial sources, referred to organic matters (organic matters as in biological compounds or molecules, like lipids, hydrocarbons, amino acids, any one of the 5 possible nucleobase molecules, carbohydrates…not cells, and not living organisms), that from asteroids, meteorites, comets, planetesimals, etc.
In 1969, two large meteorites (both made of largely carbonaceous chondrite) have crashed on different continents.
- One in Chihuahua, Mexico, the Allende Meteorite (over 2 tonnes ).
- The other, Murchison, Victoria, Australia, the Murchison Meteorite (100 kg).
No living cells and no living organisms were found in either meteorites. However, both meteorites showed abundance of organic evidence, of those “organic matters” that I have talked about.
The thing is that these organic matters were found preserved within meteorites, protected from terrestrial contamination and from cosmic radiation exposure.
Plus, the Allende Meteorite (at 4.567 billion years old) is over a hundred million years older than the Earth itself. While much of the Murchison Meteorite is roughly about the same age as the Allende Meteorite, HOWEVER, some grains of silicon carbide have been definitively dated to be 7 billion years old.
Amino acids are the most important biological compounds, as 22 different types of alpha amino acids, as they are the building blocks for proteins, hence these types of amino acids are known as “proteinogenic” amino acids. These 22 types existed naturally in life, as these can be found in genetic code. Of these 22 amino acids, 15 of these amino acids were found in the Murchison Meteorite.
There are actually over 500 different types of amino acids. Some of those found in the meteorites, don’t exist in nature on Earth, hence they are of extraterrestrial origins.
But here, is what do know: not as higher concentrations than the amino acids, purines and pyrimidines were also discovered, from the Murchison Meteorite.
If you don’t know these organic compounds are, they are base pair of the nucleobase molecules.
In purines, the pair is adenine & guanine.
In pyrimidines, the pair can be either cytosine & thymine for DNA, or cytosine & uracil for RNA.
Even more abundant is carboxylic acids, which is essential component to fatty acids, and fatty acids are essential to make up of lipids. And lipids are essential cell membranes.
With these evidence (the 2 meteorites), organic matters existing outside of the Earth itself, is a definite probability, hence cannot be dismissed.
When scientists are talking about extraterrestrial, they are not talking about ufo spaceships.
And btw, please answer my earlier question. Who is the scientist you’re referring to, about the ufo?
