If the apocalypse was coming and you had a choice to pick it what would it be zombies, aliens, robots, or another?

If the reason for the apocalypse was aliens or robots, we wouldn't stand a chance. The threat to humanity in the case would be a form of being with the level of intelligence humans haven't reached yet. No matter what we plan, they would always be two steps ahead. Like a bunch of sheep trying to escape from the shepherd. Our only advantage would be our population, that too, presuming the fact that the alien invasion would not be of a large scale. Zombies on the other hand are dumb and slow considering the common perception of what they are. Beating them is a question of the human ability to find an antidote and controlling the spreading of the virus, and endurance through the apocalypse until an antidote is found, unlike the previous case in which the whole human population would have to evolve into a more intelligent form of life and if not, would be a form of life easily exploited.
