If our planet did not rotate, we would have a sunny side and a dark side of the Earth.
On the dark side, we would know what we looked like, but not have much idea what lay beyond the lamp`s light. We would not know what the Sun looked like until we travelled to the bright side of Earth.
On the bright side, we would not know what a beautiful star filled sky looked like. We would not know what the Moon looked like.
We would need to carry our phones to be able to check what time it was?
There would not be much credence given to the idea that time existed as a real thing, presence, or force.
