From the point of view of an observer on Earth, muons produced high in the atmosphere have a very short lifespan due to their high energy, meaning they decay quickly. However, muons travel at relativistic speeds, which causes time dilation. As a result, these muons experience time more slowly than an observer on earth. This 'extra' time allows the muon to travel a greater distance than expected before it decays, making it possible for the muon to reach the ground.
