I don't know where to begin because I don't know for sure where the zombies began. Some say they started with the black magic of witch doctors in Africa. Others insist it had been Haitian bokor sorcerers and their curses. Still others claim a virus that occurred naturally started it all. Before world wide communications and then USA internal communications and media shut down, there were rumors the virus had been developed by Muslim religious fanatics. Maybe that's why those western Asian countries were affected first and their populations annihilated first. Then the religious zealots here professed the very God they worshiped unleashed the zombie on all of us because of our greed and corruption. I'm not a religious person, never have been, but I find it hard to believe any God revered by large numbers of followers would wipe out an entire planet for the sins and atrocities of a few. But after what I've seen and been through, what do I know?
