UPDATE 6: The Earth has 5,500,000,000,000,000 tons of atmosphere. If we lose 550 tons of atmosphere per day, it would take 27,397,260,270 years to lose all of our atmosphere. If we didn’t have meteorite disintegration making up for atmosphere loss, in 1,000,000,000 years we would still have 26,397,260,270 years before we lost all of our atmosphere.
