Theists have just as much "proof" against trickster gods as they do promoting their intended ones, simply because they have to use their holy texts as evidence.
"I get angry when believers say that the entire unimaginable hugeness of the universe was made entirely for the human race, and atheists by contrast say that humanity is this infinitesmal eyeblink in the vastness of time and space, and then religious believers accuse atheists of being arrogant."
