If the truth were out there, then you could be content with finding it. You would not require any intelligence, it would hit you in the face. There is a miriad of truth of course, some relevant to your search, some not. But we don't actually know everything, so you cannot find all the facts. Fortunately, we have a brain that can link points together and arrive at a picture. Unfortunately we have desires that are not condusive to recognising the leaps of faith needed in linking the points. Too much reliance on fact will not lead to the truth. Consider the Big Bang, first put forward by the Very Rev. George Lemaitre, not Prof. Hubble BTW, he confirmed it. Now an examination of this, the first happening, will lead to the truth that there is a supernatural being. There is a sequence of logic that will take you from that point to Jesus but that is only half what is required. Why are we here is not included. The hand of man is too often mistaken for the work of God. Polarisation of ideas separate the less than perfect from the less than perfect.
Don't give up.
