I believe we should be friendly to aliens, if they do exist in the universe. It is more likely that they will visit our planet, as they might have more advanced technology which makes long distance travel in space possible. I donât think the aliens will try to destroy our Earth or rule the world, making everyone their slaves. Think about how we humans want to be treated if we land on other planets. If they come to the Earth one day, we should welcome them. We should be happy that we are not alone in the universe.
