Have you seen the movie Europa Report? I don't want to spoil any part of it for you, but it's really good. If you have Netflix, it's on there.

I have this vision of dinosaur astronauts, clinging to the rock that has been ejected into space, on their way to Mars to establish a new life there.

I have always found the pan-spermia theories interesting. It still doesn't answer the 'where first' question but it allows for many places to share similar lifeforms without requiring a recreation of an improbable event in all of them. Of course it would be really weird if the universe was populated in this way with humanoids, and the original Star Trek was closer to the truth than not :-)

What if life on earth was also just a fragment of another past planet?

Is it realistic or do they find aliens/god?

Even if organisms got ejected with rocks, wouldn't they just die frozen or from radiation on the long journey thru the vacuum?

Not necessarily. It's worth reading the entire article. We've observed small life surviving raw space exposure before.

TFA: "Three metres is the minimum they think necessary to shield microbes from the Sun's radiation over a journey lasting up to 10 million years."
