The correct answer to this open question is the following.
According to Descartes, the responsible for finding out the truth was oneself and the mind when it states "I think therefore I am." French philosopher, Rene Descartes's approach to the truth had to first, express doubt.
Those responsible for finding the truth were supposed to complete this task by doubting first, questioning their own existence. Then, through the mind, the reason, confirm their existence because they had the capacity to think.
I think the truth cannot be found in one religion, such as Christianity, Catholicism, or many others, because those are dogmas developed by people through different eras. The truth depends on the perspective of every individual. There is no single truth in life that apply to all the people around the world. Diversity is the name of the game, and that is the reason why many religions exist to satisfy people's spiritual necessities. If we do not respect other people´s teachings, truths, and necessities, that is when problems arise.
