Technically it IS right. “The exosphere is the outermost layer of Earth’s atmosphere (i.e. the upper limit of the atmosphere). It extends from the exobase, which is located at the top of the thermosphere at an altitude of about 700 km above sea level, to about 10,000 km (6,200 mi; 33,000,000 ft). The exosphere merges with the emptiness of outer space, where there is no atmosphere.”
Actually, even space beyond the exosphere is not devoid of the occasional hydrogen atom, etc., so its a matter of deciding when to call it space.
To say the atmosphere is so thin you can’t breath in low earth orbit, is a bit of an understatement, wouldn’t you say?
