Individuals who scan for outsiders on Earth are likely reasoning of minimal green men and flying saucers in the sky, yet imagine a scenario in which they ought to take a gander at limbs in the ocean. A current paper guarantees that octopuses and different cephalopods have their birthplaces on an alternate planet, brought here as eggs on some space rock in our planet's removed past.
It's an entirely fantastical thought, and in all likelihood not genuine, but rather the possibility of life on Earth starting from elsewhere isn't as totally ludicrous as it may appear. The thought is called 'panspermia,' and keeping in mind that there's not a mess of proof supporting it, it's likewise not feasible.
Panspermia, extensively characterized, is the possibility that living creatures or hereditary material can go between planets in our close planetary system, and even between our close planetary system and adjacent stars.
Some living things—like tardigrades and certain types of microscopic organisms and parasite—can get by for broadened periods in the vacuum of room. A trial on the ISS found that various organisms survived fine and dandy in space for about two years, and it's nearly ensured that a few animal varieties can get by for more. Truth be told, microorganisms making due in space is such an issue for NASA, to the point that the office has a 'Planetary Protection Officer' dedicated to ensuring it doesn't occur coincidentally.
Also, we realize that some material from one planet can end up on another planet. Here on Earth we have a gathering of rocks from Mars. No one went to Mars to get them; we discovered them here on this planet. Eventually, a space rock affect on Mars sent rocks into space and some of them discovered their way here.
All it would take for life to make a trip from Mars to Earth—or the other way around—would be for a space rock to affect a site with a few microorganisms, and for those living beings to survive the effect, getting launched out into space, quite a long while circling the Sun, and re-entry and arriving on an alternate planet.
The majority of this is far from saying that octopuses are outsiders, which is, to understate the obvious, is merely an extension. Octopuses advanced here alongside everything else. However, it doesn't mean the more extensive hypothesis is totally infeasible, and it might be worth considering sooner or later, particularly on the off chance that we figure out how to discover life somewhere else in our nearby planetary group.
