Outer space begins 100 km above your head. It is an arbitrary line called the KÃ¡rmÃ¡n line which has been set for treaties concerning space. There is indeed no firm boundary where space begins. See: https://thehighfrontier.wordpres...
The atmosphere becomes thinner and thinner with increasing altitude, with no definite boundary between the atmosphere and outer space. The KÃ¡rmÃ¡n line, at 100 km (62 mi), or 1.57% of the Earth's radius, is often used as the border between the atmosphere and outer space. Atmospheric effects become noticeable during atmospheric reentry of spacecraft at an altitude of around 120 km (75 mi).
