The shape of the octopus does look strange. This creature looks like a lump of slimy jelly with two eyes and protruding tentacles. Maybe because of the appearance of the octopus like that, some suspect it to be an alien.
Quoted from Wionews, a study says that octopuses may have fallen to Earth from space in ice bolides or comets containing ice hundreds of millions of years ago.
We know the accepted scientific view of the origin of life on Earth. But Panspermia, an argument that life was 'brought' to Earth by celestial bodies such as comets, has also attracted strong interest among the scientific community.
In our search for life in outer space, we often look for the presence of water or comets containing ice. Therefore, it is at least theoretically understandable if one proposes that life forms, such as microbes, were carried through space in comets and brought to Earth.
Studies of octopuses show that cryopreserved eggs, whether squid or ice-preserved octopuses, could have arrived on Earth hundreds of millions of years ago.
Cryopreservation is cryogenic preservation, which is the process by which organelles, cells, tissues, extracellular matrix, organs, or other biological structures that are susceptible to damage due to disordered chemical kinetics are maintained by cooling to very low temperatures.
This study paper on octopuses was published in the journal Progress in Biophysics and Molecular Biology in 2018. This research actually sheds light on the origins of life on Earth. In one of the discussions, this study also examines the existence of octopuses on Earth which are claimed to have come from outer space.
It's important to note that the scientific community has yet to find solid evidence that octopuses came from outer space. The study is also published in a peer-reviewed journal, which means it has not been peer-reviewed.
