Why Why?

[Ferrocyanide]

Why is it so important for human beings (some more than others) to find an answer to the question of why we exist? 

I can see all the usual responses:

• My life doesn't have meaning otherwise
  
• I won't feel fulfilled without having a purpose
  
• I need to know what happens when I die
  

Theists fill the void with the concept of an omnipotent being that magically has all the answers.... apart from it doesn't.

To the best of my knowledge, Christianity does not provide a reason for our existence, other than saying God created us but his purpose is so unknowable and obscure that we shouldn't ask.

How is this any better than saying "I don't know"? Ie. instead elevating all provided answers to the important questions to vague "we cannot guess the will of God" bullshit.

The main criticism Theists have of science is that it can't / doesn't attempt to answer the ultimate question of "why" teleologically, which is correct. However nothing in religion answers anything either other than supposedly giving an answer to "How" we came to be. 

Coming back to my original question - why is it so hard for most people to deal with uncertainty and ambiguity, that they would rather clutch at any explanation (no matter how vague, unfulfilling and unlikely under even modest logical scrutiny) than be truly comfortable with simply not knowing? Is this just plain and simple human nature?

1. I think it is because we are emotional machines. All animals are emotional machines.
2. An important emotion is fear (fear of pain, fear of disease, fear of a predator, fear of death).
3. I don’t know if every animal recognizes that they will die but I think that they all have fear of pain, fear of predator.
4. Humans are brainier than the rest of the animal kingdom and so, they have developed language, abstract though.
5. The combination of 1 to 4 leads to humans inventing a solution to the problem of death: the soul
6. Stories about gods, angels, demons and what they do in their free time is irrelevant. The important component among all cultures, all religions is the soul.
A god that doesn’t offer even a slight possibility of eternal life is a useless god. (Well, there are certain gods in african culture and you can make deals with them, so they have some kind of use.).
Which religion claims that when you die, you become worm food and that is all?

My life doesn't have meaning otherwise
I won't feel fulfilled without having a purpose
I need to know what happens when I die

Those 3 lines have to do with death.
When someone asks “What meaning does life have according to atheism”, what they really mean is “If you are just going to live 60 to 100 y and die and you become worm food, than life has no point.”
Remember Pascal’s Wager? He created that table, it’s basic game theory. Remember what value he gave if you are a non-believer and you are correct?

The theist is not interested in purpose. He is interested in not dying.

A hammer has a purpose. An intelligent being created a hammer so that he can push nails into wood.
A watch has a purpose. An intelligent being created the watch on order to synchronize events, etc.
A VCR has purpose. It records your favorite shows.

Purpose means job or function.

What’s the purpose of a human according to judaism?
Is it the human’s job to say “What a great god!”? What’s the point of that?
That’s the kind of thing that a king might want to hear or a narcissist would like to hear.

The main criticism Theists have of science is that it can't /doesn't attempt to answer the ultimate question of "why" teleologically, which is correct. However nothing in religion answers anything either other than supposedly giving an answer to "How" we came to be.

If they are not satisfied with the goals of science, then they can shop elsewhere.
Science’s goal is to satisfy our curiosity, to learn how things work, to collect data, to understand nature.
It isn’t to make anyone comfortable, it isn’t for making some product, it isn’t for saving lives.

SUMMARY:
It has to do with psychology/emotions/fear/end of life.
