I once visited a village of primitive people.
At village, I felt time and life moved slower.

One of many reasons why some people today are very difficult to accept the existence of advanced technology in prehistory era is because they didn't realize that their minds have already been clouded by an unconscious presumption which states 'ancient people should be primitive, before gradually evolving into this modern era nowadays'. I call this as 'Toba Syndrome'.

Put on all state of the art technologies as we have today and then pay a little visit to a primitive race deep within an unspoiled forest. Only one of these two events would happen, they will try to kill you, or, they will treat you as their new god.

Mental strength induces mind and body.

Plan may fail, life goes on.

Let us think for a moment about alien, regarding possibility of the existence of other civilization beyond our dear planet earth. We probably conclude that it's all just hoax, or some rumors issued by ruling government for some purpose. Now, we can contemplate a bit about it by asking this simple rhetorical question, 'How could possibly people be able to think about something unknown, which have never been popped out in human minds at all?'
