Why Creationists don't realize the biblical Creation is just jewish mythology?

[Amarok]

First you said that "fundamentalism" -- which you still haven't defined -- can't leave things of lasting value.
Then you said it can, but the cost is too high. 
These are different points

Wow dishonest 

Any one can create value by incurring costs far in excess of the value it creates.   That is called net value destruction regardless of the nominal value of what it leaves behind.   Value destruction by nature is easy to do,  which is why the unscrupulously greedy always resorts to it when they find they can claim credit for the small results but dodge responsibility for the footing the big bill.    

 Value creation occurs only when what is produced to leave behind cost less to produce in total than its own value.  That is far harder to do.  To ensure results for others justify cost to others is what good stewardship means.

Fundamentalism is a value destroying proposition of a very high order.   The fact that what it leaves behind looks impressive by itself does not change the fact that these values are trinkets next to the incalculable cost to humanity of sustaining the fundamentalism.    Fundamentalism exists to serve its creed, if it were less dishonest, and the fundamentalists, if it were more typically dishonst.  It is not there to serve those upon whom it hoisted itself.   Hence it gives no real thought to stewardship of most of those whom it involved.   It but seeks magnify the glory of its creed by exaggerating and claiming credit for everything it can whether it was responsible for it or not, while passing as much of the costs to others as it can.
