If “gravity” is credited with being a force strong enough to hold the world’s oceans to the surface of a rapidly spinning ball, then it is impossible for “gravity” to also simultaneously be weak enough to allow butterfly's, birds and insects to defy this all-powerful force and travel freely unabated in any direction.
If “gravity” is credited with being a force strong enough to curve the massive expanse of oceans around a globular Earth, it would be impossible for fish and other creatures to swim through such forcefully held water.
“The ‘law of gravitation’ is said by the advocates of the Newtonian system of astronomy, to be the greatest discovery of science, and the foundation of the whole of modern astronomy. If, therefore, it can be shown that gravitation is a pure assumption, and an imagination of the mind only, that it has no existence outside of the brains of its expounders and advocates, the whole of the hypotheses of this modern so-called science fall to the ground as flat as the surface of the ocean, and this ‘most exact of all sciences,’ this wonderful ‘feat of the intellect’ becomes at once the most ridiculous superstition and the most gigantic imposture to which ignorance and credulity could ever be exposed.” -Thomas Winship.
