if we had to leave this planet and colonize elsewhere...

okay, say our planet becomes inhabitable and we gotta leave. people
remaining will all die.

the people who do leave for another planet.... no guarantee that it'll
be found but let's say they come upon a planet that may be
inhabitable.

1. suppose the planet already has inhabitants. what if they don't
allow us to stay? should we wage war like the israelites in the land
of canaan and carve out a little territory?
should we respect their wishes and drift in space til we inevitably
run out of fuel and die?

2. suppose the natives of the planet invite us but only as second
class citizens. would this be cool?

3. suppose the natives have the IQ of something like 70 and we have
the intellectual and technological power to rule them. should we?

4. suppose the indigenous animals are no smarter than animals. should
we hunt them and eat them?

5. could there be a planet that is inhabitable but has developed no
life? for example, can a planet have plentiful oxygen in the air
without plant life?

6. if we don't find a planet to settle on, can we survive on the
spaceship indefinitely by taking fuel and material from gaseous
planets like jupiter? could we perhaps download our consciousness into
computers so that we won't need food and to take a ****?

7. suppose on a planet there is a battle between two native groups,
something like ET version of nazis vs the soviets. should we side with
one group and help them and share in the spoils? should we remain
neutral?

8. what will the human colonizers and their descendants think of the
planet that was the home of their ancestors? will it totally be
forgotten or considered just some silly myth?

9. why do we bother with art, history, and civilization when we know
all this gonna turn into dust and will be entirely forgotten in the
grand scheme of things?

10. you agree that no matter what we do, it's ultimately pointless and
stupid?
