Panspermia is the hypothesis, first proposed in the 5th century BCE by the Greek philosopher Anaxagoras, that life exists throughout the Universe. It is thought to be distributed by space dust, meteoroids, asteroids, comets, and planetoids, as well as by spacecraft carrying unintended contamination by microorganisms.

Panspermia is the concept of life forms travelling across the universe by means of transmission of compressed information representing said life forms e.g. via genome coding, which can then enable the recovery of intelligent life.

⭐ VIDEO: Panspermia – The Origin of Life on Earth ⭐
There is a certain consensus, based on scientific evidence, that life on our planet began at least 3.8 billion years ago. One of the most popular theories about the origin of life assumes that primitive Earth was the most suitable place for the first organic molecules to be synthesized, whose level of complexity would have progressively increased to form other more complex ones.
In recent years evidence has been accumulating that it would not be so complicated if certain organic molecules that are fundamental to life had actually formed beyond our borders and reached Earth through meteorites.
It's said that in the 5th century AD. C, the Greek scientist Anaxagoras already spoke of life being dispersed throughout the universe in the form of seeds. In the early 20th century, Swedish chemist and Nobel laureate Svanté Arrhenius proposed that resistant bacterial spores were propelled by the solar wind from one star to another. Arrhenius even calculated the time it would take for a terrestrial spore to reach Pluto: four months. The spore would reach Alpha Centauri in only 7 000 years.
