So the earth may not be spherical, tilted and orbiting the sun then?
Yes, that could be the case.
But science has a good model of how the Earth orbits the Sun, and so far all the evidence fits this model.
If you have some evidence that does not fit this model, then the scientific model will be scrapped.
Science, creates models from evidence (or guesses), and the model makes predictions.
If the predictions do not match reality, then the model is wrong.
If reality seems to follow the model THIS DOES NOT MEAN THE MODEL IF PROVED CORRECT. It just means that it has not been proved wrong yet.
Do you have any evidence that the Sun orbits the Earth, or does your evidence fit the existing model?
