What significance did the Nile River play in the life of the Egyptians, why do they deify it?

Ancient Egypt originated on the banks of the Nile River. The river valley is the richest oasis. The Nile’s fertile silt soils contribute to the development of agriculture. The seasons, the calendar of the Egyptians are closely related to the flooding of the Nile River. The god Osiris is associated with this river. He was killed by his brother Seth on the banks of the Nile, then resurrected and became a ruler in the afterlife. The murder and resurrection of Osiris means fertility among the Egyptians. During flood periods, festivities are held in honor of Osiris. Clay figurines of the god with grains of barley are buried in the ground. When green shoots break through, it means that the water has resurrected the earth. The cult of Khnum is also associated with the Nile River. This is a god in the form of a ram.
The fertile lands of the Nile grow wheat, barley, flax, sesame, papyrus, lotus, date and coconut palms, grapes, as well as building material – tree-like acacias.
