What would happen to the earth’s atmosphere if the force of gravity disappeared?

The lack of gravity will affect everything that is vital to humans. The air that is needed to maintain life will simply evaporate, nothing else will attract it. A similar situation will occur with water: some of it will fly away due to the lack of an atmosphere, and some will evaporate. All living organisms, and even microbes, will die together with a person. Even the asteroid attack that killed the dinosaurs in due time cannot be compared with the rate of death due to this reason. Due to the disappearance of the atmosphere, the sun, in a matter of seconds, will turn all life into ash. The upper layers of the planet will also be burned, it will look like a coal.
