The thing is "what if Mars looked like Earth" somewhere in the past? Was there some kind of primitive lifeforms on that planet during the short period before it freezes? Or are those images portrait so-called fake fossils?
And even if they are portraying so-called fake fossils. Or results of some kind of chemical reactions that thing doesn't mean that this is not interesting. The thing that can form fake fossils is the proto-reactions that are forming the RNA and DNA molecules.
The very first organisms on Earth were not DNA-based. They were like bacteria which genomes were in the form of RNA. And the energy for those organisms came from volcanic temperature.
If we think that Mars lost its lithosphere and core in the cosmic impacts that mean there could be a short-time wonderful environment for forming the self-replicating molecules or pre-RNA and DNA molecules. But that period was quite short when the planet was starting to freeze and it lost most of its atmosphere.
Before the first RNA-based cells. Or even the first RNA molecules formed there was a long series of chemical reactions on Earth. That means there were the proto-reactions that formed the first self-replicating molecules. And then the first RNA molecules formed. The most interesting of those images is the image bottom right. That thing can be the "proto-DNA" the molecule that started to turn to spiral.
There is the possibility that those things are primitive bacteria. But are they formed on Mars? That is an interesting question. There is the possibility that the impacting asteroids brought those organisms to the Red planet. That thing means that there is one small possibility. The possibility is that some extrasolar asteroid impacted Mars.

There is a small possibility that Mars had an impact, with the extrasolar asteroid that could bring some kind of primitive fossils to that planet.
The idea is that the giant iceberg was released from some water planet when some sun-type star erupted as a nova. Two white dwarf stars are quite near Earth.
Those white dwarfs are Van Maanen's star (Van Maanen 2) and Sirius B the white dwarf that is orbiting Sirius A. The Sirius B and Van Maanen's star were once like Suns. If those stars had a solar system they crushed their planets. And the impact wave of the nova eruption sends debris through the universe.
When we are looking at the age of Sirius B there is mentioned the age of Sirius B as the white dwarf. And the member or "pair" of the Sirius system. But once Sirius B was the sun-looking star that might have a solar system. Then that star lost its fuel grown to a red giant and erupted as a nova. Then it faced Sirius A and started to orbit it. So the originally Sirius B was an older star.
Today we might not find the planets near those stars like Van Maanen 2 and Sirius B. And if Sirius A had some kind of planetary system Sirius B would destroy it.
"Oumuamua was not nitrogen iceberg"
The fact is that "Oumuamua" is officially the asteroid that came from another solar system. Nobody ever landed on that cosmic traveler. And that means that the "Oumuamua" stays as the "possible asteroid". There is suspicion that some kind of eruption pushed that asteroid away from its solar system.
So was Oumumua some kind of alien solar sail? The fact is that thing remains unknown. The fact is that there were no radio signals that came from "Oumumua". But otherwise, if we think that "Omumua" was some kind of recon craft or SETI-probe that craft might travel through the solar system and record signals. Maybe that kind of probe would be covered by ice that it remains stealthy. And then it can send the data to its senders. But was Oumumua that kind of thing?
But when we are thinking the "Oumuamua". The visitor from the other solar system there is the possibility. That there is a large part of water on that asteroid. And then there is nitrogen on the core. The core of "Uomuamua" is covered by cosmic dust. And I don't know did somebody made the spectroscopic research of the surface of that asteroid?
So could the origin of the Oumuamua be near the Van Maanen 2 or Sirius B? The thing is that we believe that Oumumua was not alien spacecraft. But we are not sure about that thing. But we must keep our minds open.
Before research is not completed we should not close away any possibilities. And nobody ever landed on Oumumua. And nobody ever took any samples of that interstellar traveler.
That kind of visitor from other solar systems is always interesting. But even if it's the debris of a destroyed planet. Even if the entire Oumumua has not formed of water ice, there is always the possibility. There is the water has been stored in the small pockets of that asteroid. And in those pockets could be remains of the primitive or why not also advanced lifeforms that lived on some distant planets before its sun crushed that planet in nova or supernova eruption.
