Question

theoretically if an alien from another exoplanet with a much stronger gravity from ours comes here could that alien be able to levitate/fly on Earth?

Answer 1

No, not any more than being born on Earth gave astronauts the ability to levitate or fly on the Moon. Coming from stronger gravity means you’d need to be stronger to move around, and you can jump higher in lower gravity—but the law of gravity applies to you nonetheless.
