This is a deep well of theory of society, and reasonable people disagree based on how they answer that question.

Some do believe property rights exist independent of government (and existed before the concept of governments, as webs of individual agreements between people with no over-arching enforcement authority, i.e. "This belongs to me because if you try to take it from me I will kill you. That belongs to you because you would do the same to me. We have an understanding between us, but is an understanding between two people a 'government'?").
