Entropy, for example, doesn&amp;#x27;t seem to be computable[1].

That is fundamentally at odds with most people&amp;#x27;s conception of God. The probability that the first cause (FC) is computable is basically zero, so it most likely won&amp;#x27;t have a Kolmogorov complexity. For example, not even entropy is computable[1][2], let alone FC.
