Respuesta :
#1 - Yes, there are other planets with life in our solar system. Life is not only humans but plants too. There's already a big possibility of there being plants on Mars.
#2 - Humans visiting an alien planet is more likely. We're already visiting more planets and exploring the moon with NASA and other space programs. I'm sure as our technology advances, we'll be able to go even further into our universe and explore even more than we already have.
#3 - We should try to set up a colony on Mars. Colonizing another planet could help us to develop further as beings, we may become more intelligent beings than we already are.
#4 - It depends on the atmosphere. For example, we'd need astronaut suits on our moon to fit the low gravity. On gas giants, we can't even stand!
#5 - No, I would not choose to live on another planet. Earth already has so much we need to explore, such as our oceans. Earth has been and will be our home for quite a while, we should know more about it than we already do.
Answer:
I think there is life on other planets; not tall green aliens, but plant-like organisms. I can't imagine that we're the only living beings in all of space!
As I said above, I don't think that the alien life that's out there is very sentient, so I think us visiting an alien planet is more likely.
I think that setting up a colony on Mars would be a good idea for the future, so that in future space travels/missions, if something goes wrong, they can cut their travel time short and repair or do whatever they need to do on the colony instead of risking a full journey.
If humans moved to another planet or to a moon, the basic items we would need are space suits, a spaceship, tools for farming, shelter, etc.
I personally would not go to another planet if it meant I couldn't get back to Earth for 10 years. How would I know I was going to like the planet? I don't want to be miserable there for 10 years, not to mention how homesick I'd get! Plus, I'd obviously be missing ten years of everyone I know's life back home!
