Why do you have to "announce" your capabilities to beings you designed? Why do you have to onboard them to your "program" at all? If you truly are omnipotent, simply make beings that already know, and are already with the program. Assuming that is indeed what you want, why would you do anything else?

Are you throwing in extra steps for your own amusement? Just as a prank? Why? You're omniscient. You already know how it ends. What's amusing about it?

You are either toying with beings you created to be non-accepting and deliberately presenting conditions that won't convince them, or you're lacking one or both of omnipotence or omniscience.

An argument straight from the edgy teen atheist textbook, sure, but nonetheless one I have yet to see a compelling rebuttal for.
