Lots of people are reluctant to believe what they have not believed, this is the very reason they cannot be able to know more truths. You can only know the truth by trusting your intuition in the first place, proofs of the truth will show up when the door of your heart is open. When you can only trust something new to you with presence of hard evidence, you will probably always be the last to know the truth of higher significance. The fact is, the realm of truths our technology can scientifically explain are way much less than it cannot. What we as human cannot evidence doesn’t mean that is not the truth. Believing in the first place the unknown or uncertain actually requires lots of courage, this is also the biggest barrier to knowing the truth in human history.
