In science, you can always cook up a theory to “explain” the data you've seen so far: just list all the data you've got, and call that your “theory”! The obvious problem here is overfitting. Since your theory doesn't achieve any compression of the original data – i.e., since it takes as many bits to write down your theory as to write down the data itself – there's no reason to expect your theory to predict future data. In other words, your theory is worthless.
