Answer here's my answer.
Step-by-step explanation:
#1 I do believe in UFO's, since they have some evidence of them crash landing in certain countries and they are investigating the ships and we haven't even explored the galaxy. They could be out there!
#2 I do believe that this will one day come true and advanced cultures who re-inhabit the Earth will categorize us as Aliens if we ever go to another planet and no longer live on Earth. But, that's only if they find us! :)
#3 The Mars Rover Perseverance has actually just happened! It was the day they landed on Mars for the first time and took videos and pictures of the land on Mars.
#4 To be completely honest, I'm not sure! I really would like to see them land on another planet to colonize, but if we are still having trouble with bad things here, I'm not so sure we will.
