> And beside, it's not like any other form of knowledge seeking will ever bring you truth either. Most of them can't even describe the rules of this simulation.

That is because the religious truth doesn't need to deal with the rules of the simulation. It can go meta of it. For example, the nature of how I should think and live are the same regardless of the scenario and the simulation. Virtue, for example, is universal and would be universal in all planes of existence, be them simulated planes or non-simulated planes. The rules of the simulation grant control of the environment, but have nothing to do with the intrinsic being-ness of our psychological nature, or at least not directly. No simulation provides in itself existential orientation, which is what religions aim to provide.

As for whether truth-seeking is absurd or not, without truth that becomes irrational statement. You are claiming that to be true("it is true that truth-seeking is a waste of time"). But there are different kinds of truth and scopes of truth. I do not require an absolute truth because I am not an absolute entity.
