Reading comprehension. Do you not see the word 'if' in jaybird's sentence?
The trinitarian trolls are so desperate not to concede a single point, they rely on deception and one logic fallacy after another. In this case, Appeal to Strawman. Let's pretend jaybird is making a statement that does not go with Scripture, let's pretend he did not use the word 'if' to make the obvious point that when, Elohim (heavenly beings) do things on Earth, they do so at the command of the Most High, the one and only LORD God.
In common language usage when a leader gives a command - Bush, Obama, Trump, Biden - people still give credit to the commander. It is said 'Obama bombed so and so.' They say this even though we all know Obama did not literally bomb anyone. Such figurative use of language is more concise. God gave the order and the angel destroyed the first born males of Egypt. God gave the order and an angel destroyed Sodom and Gomorra.
