So the naive feeling is if you just try to come up with a quantum theory of gravity that's well-defined, you need an infinite conspiracy between what the gravitational field is doing at high energies and what all the other fields are doing at high energies. It turns out string theory gives you that infinite conspiracy because it's just one thing, a string, that's vibrating in different ways.
