-.- 1. It's called carbon dating, we have found fossils that are hundreds of millions of years old. Not only that, but you can also date things using the half lives of radioactive materials 2. The sun changes size based on the seasons due to the angle of the earth's rotation and the elliptical shape of its orbit. 3. That's not how magnetic fields work.... Electromagnetic fields travel at the speed of light through free space but through objects it drops by a certain amount depending on that on the dielectric ratio based on the dielectric free space constant. As for how I know this, I'm an electrical engineer. 4. I really hope you're trolling and not actually this ignorant.
