Why has some Muslim terrorists destroying Egyptian findings?

pre-islamic history is filled with shirk and pagan practices that we Muslims reject and they should be destroyed. The Islamic scholars have stated that the kufar want the Muslims to be interested in that pre-islamic pagan history in order to weaken them in faith for example. So the kufar have an agenda here, so we Muslims should not be interested in pre-islamic history at all whatsoever.

perhaps they are intimidated by history that predates islam

they are totally scared that their evil beliefs are threatened by pre islamic history so they desperately want it erased

probably want to erase the achievements and contributions non muslims have made to the world by erasing records of them so they have an excuse to belittle non muslims and build up their own importance

if muslims keep track of their own contributions but attempt to erase the contributions of others they can make their group seem more important than it actually is
