OK, here’s where they reach a shaky conclusion: “The conclusive evidence that the SNC meteorites originated on Mars comes from the measurement of gases trapped in one meteorite’s interior. The trapped gases match those that Viking measured in the martian atmosphere.”
That only “proves” the gases match. For ONE meteorite. hmmm is THAT good science?
It enables a fun hypothesis, NOT a conclusion.
Still it would be nice to GO to MARS and prove/dis-prove all this.
From my first link:
“and now in at least five other Martian meteorites [on Earth].”

I, too, am suspicious of the “gas match” in a 4 billion year old rock. Earth’s atmosphere has gone between 0 and 35 percent oxygen over the last 4 billion years. No way would an earth rock on Mars match today’s earth’s atmosphere, so why would a rock from Mars’s distant past match today’s Martian atmosphere, and if it did, how could there have been a living microbe in the area to get trapped in the same rock with it?
