you only think it's a fact there is something else outside of a planet, which you also assume is a fact that you live on a planet. These assumptions sound silly to people who use critical thinking when researching the truth!
There are no planets, no space exploration, no dinosaur bones, no evolved monkeys or other kinds, no gravity... There's only lies that you fell for that you back up with assumptions of truth, though you've never seen or proven any of these things exist.
