We as curious beings tend to be on a search for an  "interpretative pattern" that gives our lives a meaning, making faith somehow a natural trait human beings possess.

Faith according to Wikipedia:
faith
/feɪθ/Submit
noun
1.
complete trust or confidence in someone or something.

2.
strong belief in the doctrines of a religion, based on spiritual conviction rather than proof.

Faith can be influenced and reinforced by your enviroment, which includes your family, teachers, friends etc. To put in a nutshell, everyone you're surrounded by.

However, we live in the 21st century and science, which has come a very long way is now capable of explaining some things that had before been unexplainable, resulting to God's contours/outlines getting increasingly blurred.

The more science is able to explain, the more people lose their faith and the more become atheists.
This doesn't change the fact that there is still a lot science in unable to explain. Science in most cases is only capable of describing things rather than [b]explaining [/b]them.

Sometimes we find ourselves in a hopeless situation, where science or technology is unable to save or help us, for example when someone gets diagnosed with a deadly disease or someone dear to us in a coma state or a persistent vegetative state or even if that person happens to be US.

It is during times like this we tend to hold on to sth or someone like God (or as atheists will say say, a "sky daddy" ), who might still be able to save the day by miraculously healing the person.

Although, most people are guilty of these (including some atheists, who ask for a pastor on their deathbed), situations like this are very common in developing countries, where most times all people have is "hope".

The more developed a country is, the more its citizenns tend to see God as someone people needed in the past to explain the unexplainable, a person who is however becoming less relevant in a world where science and logic is now used to explain the world.

But how less relevant can he become?

Because despite all of these, there is still a large number of people in developed countries, who still confess to some sort of spiritual belief, such as a life-force or divine spirit that pervades nature and humanity leading to the questions:  

1) Are you of the opinion that there'll be a time where reliigion becomes history?

2) Don't you think it is human nature to try to explain the complexity and unpredictability of the world by believing in sth. spiritual etc. ( even when there is none)?
