Xians used to think that their sky daddy controlled the planets however we now know that they orbit in a mathematically predictable manor.
The causes obvious problems as a year is linked to how long it takes the earth to orbit the sun and so it would be impossible for your sky daddy to change how long a year lasted as and when they felt like it.
So what if i prayed that Christmas would come early this year? If your sky daddy could not answer my prayer then there are prayers that cannot be answered however if they could then they would break the laws of science. I think those theists are going to be stumped by this thought of mine.
