Often theists try to prove there is a god by stating that the universe needs a creative force. Whatever the strengh of this argument may be, There is no reason why such a creative force should have any qualities we attribute to god.

In particular the idea of an omniscient god is quite laugthable. Attributing infinite knowledge to god is attributing a antropomorphic quality. Knowledge is only the attribute of some very scarce and complex life forms, humans in particular. Attributing it to god makes sense in a very narrow minded self centered stone age.

Nowadays, we know how humans are a just a ridiculously small part of all that lived. We also know how life is scarce in the universe. Clearly, the universe is not focused on us. And from that, attributing the creation of the universe to a being to which we also attribute qualities derived from ours (like knowledge) is kind of ridiculous, and in contradiction to what we can see outside of our small world.
