Wow. This is a uniquely horrible argument with very little thought put into it.
We hunger, and food exists. We thirst, and water exists.
Tell that to anyone dying of thirst or hunger.
We feel horny, and sex is real.
Ok, so who is responsible for the guinea worm? Who willed that into existence?
This isn't a logical argument as much as it's a vapid bit of poetry, akin to "look at the trees." Thus it's not easy to debunk it with a logical argument, because any rational plea you could make can be hand-waived away with as little thought as went into the initial statement. Everyone is providing absurd counterexamples, which I think is a good way of showing how absurd the original statement is, but I think you'd do better if you pushed the speaker to form their argument into something more structured, to move away from wishy-washy nonsense and towards something that can be broken down and discussed. Otherwise your conversation will forever be stuck in the realm of "it just feels that way."
