Ok first of all they never worshiped their kings and queens; the kings and queens i'm thinking you're referring to is their pharoahs which were their leaders. They worshiped many gods and goddesses which meant they were polytheistic but no they don't worship these gods and goddesses anymore.
There still are kings and queens and probably still castles but I think you're referring to the medieval time.
yes
They still exist in Europe.
yes modern Egypt does have pyramids
The fact that the Great Pyramids of Giza are still standing, 4,500 years after their construction... not to mention the Sphinx and the Valley of the Kings...
This is hard to say, as many countries still have Kings/Queens,But i think that there are more presidents of countries than Kings.
No, Brazil has been a republic since 1889.
yes
king and queens still do exist in England an all of Europe .the kings and queens will dress fancy there queens will dress with ornate dresses the kings of crowns
Because they want to still look powerful after death x
That is a very good question. Where there are still kings and queens, yes, because the princess is the queen, then she gets to marry a lucky guy to gets to be king. In places where there are not kings and queens, no, because we vote to see who will be president.
