why is jupiter so gassy?

Jupiter is such a gassy planet but do you know why? Well, its because of the aliens. I but you thought that they didn't exist but they do. Not the abducting type but the friendly one's that never invade Earth thats why we don't know about them. Any way, the aliens that are on Jupiter are incredibly gassy. they can't go for more that 5 seconds without farting or burping. they don't smell that bad but it makes the surface of the planet misty and foggy. Well now you know!
