Not near vacuum. Try again.

Obviously, bacterias that thrive in human-friendly environment won't
thrive on Mars surface.
Obviously.

But we can't know that some bacterias on earth
might be able to adapt to Mars and thrive in/below the sand.
Again, how about an example. Still waiting...

Tardigrades are water bears. They survive space conditions.

Enough?

I could go on...

I call bull****.

You're the one who used the word "thrive". These are *not* examples of
bacteria thriving under something close to Mars conditions. These are
examples of them surviving exposure to vacuum, but they weren't growing,
weren't reproducing, and etc. They were essentially dormant.
