Space Travel? I have questions

If I could travel to a faraway sun, Would it be worth it? Would it be fun? Would the planet I land on have breathable air? Or would I need oxygen to breathe while I'm there? Would there be anything cool there to see? Maybe an octopus, maybe a tree? Would there be people who look just like me? Or would they have four eyes? Or maybe just three? Do you think we could find something to eat? Maybe some veggies, maybe some meat? Maybe some ice cream? (That would be neat!) And some fresh Mac and Cheese would make life complete. I know there would be so much I would learn, And once I have learned it, can I return? If I were to travel to a faraway sun, I think it would be worth it: It would be fun! Pogo
