Curious why that would be "dreadful" and I thought most assumed there is most likely water and life on mars (microbial that is), but just under the surface and with the unimaginable number of planets assuming we are the only planet with life would probably be similar to the early thinking the sun resolves around the earth.

Terrifying, because if life forms on any planet even roughly like Earth, the idea of aliens showing up one day and killing us all is suddenly horribly plausible.

If microbes from Mars seeded Earth or vice versa, then finding life in both places doesn't mean the odds of it arising are higher than we thought.
