mars rocks or earth rocks
Rocks have been found on earth from Mars.so one must assume that rocks from Earth have found their way to Mars. So could Bacteria have travelled with these rocks, survived, only to be discovered by future explorers on the red planet and declared as Martian life and really it would be ancient Earth life?

It's possible but I'd say highly unlikely.
Most of such rocks are likely to have been put in orbit during the Hadean or heavy bombardment period and there's no chance that life could have formed then.
It would also have to have survived for thousands if not millions of years in space and although some extremophiles have survived space it's a very harsh environment with a lot of UV and that period of time it's pretty unlikely.
Add those two together and I'd think winning the lottery was more probable

I think (and Geology is not my strong point) that you will have trapped gasses in the rock of the Martian atmosphere.
