Sphere Top and Bottom

Im having a really hard time trying to figure this out, Ive been looking at all the tutorials I could find and still I get the same result. What am I doing wrong?

I`m trying to create a UV Mapping of Earth on a Sphere in Blender, but the top and bottom of the sphere always becomes like the images posted below. Same thing is visible even when I import to either Unity or Unreal. What can I do to get rid of this?




I have tried Sphere Projection, I have tried marking seam at the side of the sphere, I have tried removing top and bottom to only have it merged again, and Ive tried changing the vertices manually, nothing works. Please can someone explain to me in detail what to do, without getting the result Im getting?
