Arguing with religious belief is a dead end and a waste of time. Still...
Do you understand greenhouse gas theory? Yes, the majority of heat energy that drives the heat engine of the climate comes from the sun.
But the suns heat energy falling on the planet isn't changing. We measure that, and take it into account in the models. We have been measuring solar output since the 1800s, as I understand it, and our measurements over the last century are well known, commonly available, and absolutely clear - the sun's output has not increased, the amount of insolation falling on the earth has not increased. The sun has been consistent, it is not changing, and the orbit of the earth is not changing in any unusual or rapid way.
But, since we started burning larger and larger amounts of fossil carbon, a tiny percentage less heat energy from the sun can escape every year. The surface of the planet is slowly warming, and millions of measurements collected over the planet seem to be confirming this slow increase of average temperature.
So yes, the sun is the source of the heat - but what has changed in not the sun, but the amount of carbon dioxide. methane, and other greenshouses gases in the upper atmosphere.
Saying it's the sun is like saying it wasn't the fall that killed someone who jumped off the building, it was gravity. While true, it's meaningless, and inherently deceptive.
