Oh I would not mind flying the comet thing, would want to have a say in the design and food chosen though.
but it will take generations to reach any target destination.
So you have to bring whole families ,
or as things go now, just some skin and have a computah hatch you
and teach you when growing up near the destination.
Makes you wonder if the first life on earth was brought here in a similar way 
(circular reasoning).
Us being just a chemical process; it is likely everywhere where conditions allow.
The galactic background noise being the combined radio signals from all those civilizations...
We know so little, like an ant in the garden knows about the garden, the designer of the house
th roads, their purpose.
Just a few neurons in the huge universe.
OTOH everything is connected, move an electron here and in time it affects electrons everywhere.
