The following argument people always find highly controversial but I think that it must be said here.
When you say something like "Does God really exists?" large number of people will give you the look and they will find strange that someone says that he is an Atheist. But somehow they will get over it.
But if you start a debate "Do countries really exist?" you will encounter much bigger resistance.
That is because they are connected to their state in many ways: economic , emotional , sense of attachment and .....
So, can we say that all those countries really exist or they are just product of our imagination?
I say that they are product of our imagination because of large number of reasons.
If I become citizen of another country did I also become member of the nation, what if I just learn the language and spend my free time there as a tourist? Am I capable of making someone pregnant in that country?
Now someone could say that they have a culture they have a language that they have (many other things)
But culture changes as times go by ,so the culture you are actually “worshiping“ did not exist 50 years ago and it will not exist some 50 years from now.
Same works for language.
Then someone could say “Yes but we have permanent values, such as constitution “
In that case I could say “Let’s be realistic. Do you honestly believe that someone will follow that constitution in the 8397. century?
That constitution is not even 3 centuries old and it has trouble regulating many things that existed in the times when our grandparents were young. Plus the rate of progress is accelerating.
Also, if it happens that one day sky opens up and Jesus comes down to Earth once again I guarantee you that this constitution will not mean anything to you in that case. “
So can we say that overwhelming majority of world population is not thinking straight?
I think we can, and that the person must have many properties that he/she does not starts to think in this direction.
I mean this is accepted all over the world and no one is questioning the sanity behind entire thing.
This is one very good example of how people are using their feeling in the wrong way and they claim that they can make the right choice.
