ELI5: The first law of thermodynamics states that energy can neither be created nor destoryed, only transferred. How come the second law of thermodynamics, infinitesimally increasing entropy, doesn't contradict the first law?

Because entropy is not the destruction of energy, rather a measure of the destruction of USEFUL energy, Exergy. The energy still exists somehow, but is no longer present/available in any meaningful way. By the second law, entropy may me generated, but never destroyed.

Edit: so in short, energy isn’t destroyed but rather lost from US. Entropy is essentially chaos induced by thermal processes, and can never be reversed.

Edit: sorry if I’m unclear. A good analogy would be a a battery. Exergy is the charge in it, which can be used to power a remote or dildo or something. When you use the charge in the battery, you might feel it warm up. The heat escaping the battery comes from it but is not useful anymore, thanks to entropy.
