are we all aliens?

The bombardment of meteorite 4 billion years ago may have triggered life instead of destroying them on the surface of the globe.

Never before have the scientific community felt that they were reaching the goal of the school to find the source of life on Earth like now. Charles Darwin has done wonders to explain the biodiversity of natural selection theory, but even British genius has not found the answer to the emergence of life on the green planet. After years of searching without results, experts questioned whether life on Earth originated in the universe, and the current humanity came from distant planets? To the astonishment of experts, more and more evidence supports this hypothesis. The latest study, which focuses on a type of meteorite falling in Antarctica, also shows that the origin of life may be somewhere in space.

The Earth once suffered from massive attacks of meteorites from space

The results of meteorite analysis in Antarctica have revealed an important secret. Under high pressure and temperature, these stones have been forced to release nitrogen-containing ammonia , a key factor for molecular duplication, leading to DNA and molecules that play a central role. for all species. " These special meteorites are preserved inside the ice and are discovered in their original condition ," Telegraph quoted lead researcher Sandra Pizzarello of Arizona State University. Experiments show that ammonia nitrogen is released from meteorites made up of unusual isotopes, proving that they are derived from extraterrestrials.

Professor Pizzarello and colleagues say that meteoric rainfalls about 4 billion years ago provided regular sources of ammonia gas, and from there nitrogen appeared more and more for Earth. Previously, experts estimated life existed at least 3.5 billion years ago. However, no one knew the time before life appeared, except that the Earth environment at the time was extremely detrimental to life. At that time, the green planet was covered by terrible ultraviolet rays from the sun, destroying in an instant any biological molecule. That's not to mention the asteroids that bombed 4.5 to 3.8 billion years ago. Now, however, the scientific community believes that, thanks to such meteor showers, life can appear and flourish to this day.
