What did the Egyptians believe about spirits? What role did they believe that the Gods played in their world?
Natasha_Volkova [10]

Answer:

I only know the first one well. I don't want to answer the others and maybe give false info.

Step-by-step explanation:

Egyptians were very well known to be very interested in Spirits and Gods.

Their whole dynasty was built on the dawn of their Gods. There were many, like the Greek and Roman Gods. One of the sun, one of the underworld....etc..

The pharaohs believed themselves to be god. (Due to their immense power)

Egyptians believed that after death there was an Afterlife. In that afterlife, there was games, other people (spirits), homes (graves). This might sound weird but in the graves especially of Pharaohs they placed beds, tables, chairs, games..etc..

<h3>Hope this Helps!</h3>
