It's actually "almost" universal. This is because a codon in one organism will code for the same amino acid in another organism. This is true almost all of the time, but there may be some small differences between, say, a human and a bacteria or between other organisms.
Everything on the face of the earth has a genetic code/composition
The genetic code is universal, meaning nearly all living organisms use the same code for translating DNA into proteins, supporting a common evolutionary origin. This allows genes from one species to function in another, exemplifying the interconnectedness of life. Although there are a few exceptions, the overall universality strengthens the idea of shared biological processes across species.
