Suppose earth did not rotate. How would conditions and life on earth be different

If the earth did not rotate, one half of the earth would be dark and the other side of the Earth would be light. The bright side would be too hot and the other side would be too cold. Also if the Earth did not rotate, then the two poles and the equator would be easily effected.

Some parts of the earth would not have light, and seasons would stay in one place and never change
