That's what many physicists and philosophers believe (especially Brian Greene - see video above). In this model, we all exist in space-time as a complete"worldline," your birth, every moment of your life, and death all co-extant. However, the seeming random nature of quantum mechanics does allow some to conclude the future may not be predetermined and we don't yet have the full picture. Until Quantum Mechanics and Relativity are finally reconciled, we won't know for sure.
