Drawing conclusions how did the physical geography of ancient egypt shape the development of its civilization?

The main geographic feature in Egypt were the Nile River and climate of ancient Egypt. The Nile River was a source for an irrigation canal. The biggest territory of ancient Egypt was a desert. However, a small part of fertile land on the banks of the Nile river made it possible for civilizations to grow. So the farmers must live near the river to work. The flooding of the Nile affected the ancient Egyptians because it was necessary for a good harvest since the floods contained silt which is good for farming.

answer; i believe that the correct answer is ( troxel v. granville);

giant impact theory - the moon was formed from the collision between earth and another mars-sized body.

colliding planetesimals hypothesis - the moon was formed from the same cloud of material as earth.

capture hypothesis - the moon was locked into orbit by earths gravity as it was passing by it.

accretion hypothesis - the moon was formed from collisions and combining of planetesimals.

i think this is right, if not and you know better let me know.
