i think that it is still growing . if you notice the temples mentioned in like kings . were forest that were cultivated into a temple . as it is told we are to worship the land skys seas and heavens . all things god made and nothing man made . I guess the catholics missed that part as well . but if those materials are what we know of . then it is still growing . but if you notice gold mentioned in the bible is not what we know as gold . the gold in the bible in one area is clear and in another it is reflective and in another it has a smoky haze to it . and there is more but i cant think of it now . christians say wen they die they will go to heaven but that is not what the bible says . i think were it says that the people that goes to heaven will make it as they see fit . is taken that if you think you will go to heaven you can say it looks like disneyland if you want . well to each there own . so what is it that you are seeking .
