So as to throw us off? There's no demonstration to that end. But okay for you.
Genesis 1:14-19 And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and for years: and let them be for lights in the firmament of the heaven to give light upon the earth: and it was so. And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also. And God set them in the firmament of the heaven to give light upon the earth, and to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good. And the evening and the morning were the fourth day.
Why would we have to make the jump from the fact that we cannot scientifically prove the age of the sun to the accusation that God would be trying to deceive us? This is again using the idea that “all things have continued exactly as they did from beginning of creation". This is exactly what 2 Peter is warning us about.
