This sort of defies the odds.
First, you’ve got to have some really hefty force to propel said rock from the gravitational pull of Mars. That would be a mighty strong volcano or impact, pushing the rock thousands of MPH straight up.
Second, you’ve got to be really accurate to have that rock travel millions of miles to the earth, which from Mars is viewed as a tiny dot in the vastness of space.
The more I observe scientists, they seem to be a credulous lot. Like Kindergarteners being trained to hold hands in a big line as they are led to the lunch room.

Also, it's likely that quite a lot of heat would be generated by this process. Enough heat to completely burn away any evidence of life, even if the rock was crawling with organisms before its ejection.
If the rock has been sitting in the Antarctic for thousands of years, how could ANY traces of chemicals consistent with life be attributed to a Martian origin?
First, it doesn’t have to be straight up. Escape velocity is scalar, not vector, as long as the direction isn’t straight at the ground. Proof that this can happen can be seen any night the moon is visible in the sky, as it’s the result of a Mars sized impact with the Earth.
Second, it didn’t need to point at the tiny spot in the sky thats the Earth, it just needed to enter the area of Earths gravitational field, which is pretty big, considering it’s the closest neighbor to Mars, and it had millions of years to be influenced by that gravitational field to finally fall to Earth as a meteorite.
You might want to learn a little science before you express your contempt for scientists.
