I came to a similar conclusion recently, and I believe that evolutionarily, the concept of identity originates from the biological drive to protect one's physical body. One then voluntarily expands or contracts one's sense of identity from there. So I did some mental experiments. Temporarily reducing my identity to not include my physical body, bit by bit. Then, what am I? My consciousness. What if I reduce it further? I lose consciousness. (But I get it back after I wake up.) What if I try to lose the sense of identity while still remaining aware? It wraps around and I become the universe. Am one with the universe. It was an interesting journey.
