I think I see the problem here. You've rejected the fruits of your own observations.
As a person living in modern times, there's no doubt you've seen photos of the other planets that have been captured by our many deep space missions. Those photos clearly show spherical planets.
But you don't need a deep space mission to see that for yourself. Just watch the moon go through its phases, or point a low powered telescope (or even binoculars} at the moon sometime, and you can easily see the spherical curvature of that body.
But if you trust a theory over what you see with your own eyes, there's nothing anyone can do to help you.
Photos or composite/artist renderings?
Like this one...
Why not use a real photo?
Or this one...
It looks like a photo but isn't.
