What is likely reason that the Egyptian statue is intact while the Greek statue is missing its head?

egyptians were more loyal to their gods or statues because they felt that they were a lead to the after life where as in greek if the person of the statue was unloyal or created sometype of betrayl then they ruined all things of theirs

In the past when a civilization lost a war the symbols and buildings of the culture were destroyed by the winning party. One of the things often broken was statues because they were often of rulers or gods from that culture. Actually, there is about an equal number for both cultures of destroyed items. It just seems that Greek items are around more because they are large marble statues that are uncovered in digs of historical sites
