The Pharaoh wasn't a god, it was a ruler. I think they had the sun and other elements as "God". Kinda makes sense to praise the sun as it makes their agriculture go.
The pharaos were indeed worshipped as literal gods. Echnaton famously negated them all except for the sun and himself as the incarnation, but after his death all was restored to the normal system of polytheistic theoraty. The sungod Ra was still important, but not the most important. It was a complicated system and very different from our modern thinking.
