I remember hearing a young-earth creationist on the radio when I was younger, and I was very impressed that he seemed to have an answer to every question except for this one. He just said that God must have created the Earth with the stars already visible. (Obviously he could have.) I've heard other people say that God just created the universe with an appearance of age -- Adam was not created as an infant, and neither was anything else.
The appearance of age argument is problematic on Earth because there would not merely be the appearance of age but also the appearance of a false history. Hypothetically, it would be possible for a mature planet to exist to be purposeful without giving a record of past events that never happened.
Examples:
1. The star issue you raise is already one of them. Light from starts that never actually existed is a false history. It also raises the question of why light would have to be created in transit so as to be viewed on earth anyway rather than no starlight visible at all.
2. Limestones comprised of shells of organisms that never existed.
3. Fossils of organisms that never existed.
4. Tectonic events shaping the earth's surface that never occurred. There is direct evidence that indicates how angular unconformities and mountains form, for examples rather than simply being placed there instantaneously.
5. Banded iron formations that represent a period in earth's history where its atmosphere lacked the free oxygen that it has in relative abundance now.
6. Radiogenic daughters whose radioactive parent nuclides never existed.
7. Meteorite craters representing impacts with Earth that never actually happened.
There are other examples, but ones like this are not necessary for an earth to be purposeful. They are indications of an actul history on earth and if these events did not happen, then that makes the Christian god into a liar.
However when a young earth creationist makes the appearance of age argument, it is like a tacit admission that scientists are correct: the evidence DOES indicate an old earth after all. The young earth creationists however are emotionally unable to accept that conclusion and are even willing to make their own god concept into a deceptive god in order for their pride in their interpretation of the BIble to be maintained.
