Why do you think pharaohs like Ramses the great built huge temples?

Why do you think pharaohs like Ramses the great built huge temples?
They built them because they believed that the gods lived in them.

Hope I helped ;)

Also to make sure the people remembered them and how great they were. Ramses II reinforced this message by building statues of himself in the temples he built or extended. The poet Shelley wrote a poem about it:

I met a traveller from an antique land
Who said: "Two vast trunkless legs of stone
Stand in the desert
Near them, on the sand,
Half sunk, a shattered visage lies, whose frown,
And wrinkled lip, a sneer of cold command,
Tell that its sculptor well those passions read
Which yet survive stamped upon these lifeless things,
The hand that mocked them, and the heart that fed:
And on the pedestal these words appear:
"My name is Ozymandias [Ramses], king of kings:
Look upon my works ye mighty and despair!"
Nothing beside remains, Round the decay
Of that colossal wreck, boundless and bare
The lone and level sands stretch far away
