Not necessarily. Ganzo and everyone else here might all be part of some Rabbi's dream. Hence we don't exist, even "if the old testament is truly the divine word of god".
Chances are, most here have lived at least 100,000 hours not including hours you were asleep. Yet, how many of those hours can you recall? Only a tiny fraction. The memories you have are quite similiar to what most people recall of their dreams. Little snippets of this and that. So how can you be certain that you aren't just part of some dream?
