Will humans ever prosper beyond our small rock?

Question:

Will humans ever prosper beyond our small rock?

Do you think that we can make it?
Before a metor impact, cosmic rays, ozone layer, floods, earthquakes etc.. destroys all life.
Even if we found another planet to colonise, we are soooo far off having the technology to get there.

Best Answer - Chosen by Asker: ultimately yes....... we have to... our survival as a species depends on this happening... gladly i think we occupy a sufficiently 'wide time - spectrum in order to cement this .'
