I think they've at least seen them survive in space. I recall reading stories of microbes surviving near absolute zero. Bacteria and spores could survive a lot, but I would think they would have to be inside a mighty big rock to survive the heat.
Some microscopic organisms are said to have survived exposure to space. But just because some of the pieces have been shown to be plausible, doesn't justify accepting the entire scenario.
I think this is a good statistics exercise too. What's more likely? That life emerges spontaneously in multiple spots of space, or that life survives inter-planetary (and perhaps inter-solar system) journeys?

I agree with you.

You couldn't possibly answer that.
