Explaining the 4 dimension world

Before I get to the forth dimension you need to understand the dimensions before so the first dimension just has length and if a living creature lived in there would only move backwards and forwards then the 2 dimension has length and width if a organism lived in this dimension it cold go up down diagonal backwards and forwards now the 3 dimension the dimension we live in has width length and depth we live in this dimension. There is no possible way to show you a 4 dimensional shape (tesseract) because we see in the 2 dimensions but we live in the 3 dimenstion just like a 2 dimensional creature sees in 1 dimensions now the only way we see spheres which are 3 dimensional shapes is because of the light coming of it also if an object was to travel backwards at the same rate of it expanding then you would not notice it was moving backwards but a 4 dimensional creature could see this . If 4 dimensional creature existed they would see in 3 dimensions and would be able to see everything and see through things even us. explaining the 4 dimensional world is strange if we were to meet 2 dimensional creatures they would find it hard to imagine the 3 dimensional world just how we find it hard to think of the 4 dimensional world.
