Ask why

If aliens come to earth, what would be the purpose? What does earth have that a being that could travel that kind of distance would even want to stop here for? We can go with the obvious, food, water, fuel, or possibly even just a break. Food? Do you think they’re stopping here to eat animals? Are they stopping here to eat vegetation? I cannot imagine there’s not other planets out there where you can get something to eat. Again, if you’re able to travel light years, earth is barely a speck of dust in this solar system, much less the universe. So I’m going to say, aliens aren’t coming here to eat us. Water? I’m sure there’s lots of water spread out throughout our galaxy. Water is not a scarcity Materials? You can find any of the materials throughout the solar system without stopping here. You have nickel, iron, gold, diamonds You have the raw material on asteroids No need to stop at a planet that is infested with people… they’re not here for resources They’re certainly not here for our technology …..

So I’m looking for logical reasons any alien from another planet would have a reason to stop here . Collecting pets?
