No humans needed for this trip to Proxima Centauri.
Just send a “Noah’s Ark” ship, full of many different life species, animal and plants and germs and viruses and bacteria (and whatever other lifeforms there are).
Then, let “nature” take its course...
And “in due time”....
VOILA!!!!!
Humans would have evolved from those original travelers.
(Ask the ‘Darwinists” how that works; we humans on Earth are they descendants of a similar space ship that came here billions of years ago.) ;)
Since I’m a Risk Management/Finance geek who does projects for banks, I actually understood what he was talking about!
(I should probably duck now) :^)
