Suppose the asteroid is much bigger than the one that ended the dinosaurs.

  If the Earth is completely destroyed, the humans on space ships wouldn’t survive either. There is no self-sustaining off world colony currently, and there most likely will not be in the lifetime of anyone alive today. At such time that there is, bacteria, rodents, and other life will likely come with humans as humans build the biospheres that we need elsewhere.

    With a few years to prepare, the humans would have a chance IMHO.
