You detect it with your senses.

If you wanna be a retarded little wannabe philosopher though, you pretend to be deep and ask "but what if nothing we sense is real and it's all just an illusion and we're in the matrix or something? I've got no actual reason to believe that, but I thought of it and there's no way to concisely prove it's not true, so I'm gonna believe it"
